Dunno whether this will ring a bell. This happened once the other day,
and I just ignored it. It has now happened again.
I am editing a file, doing nothing special. Suddenly when I try to type
a char Emacs asks me (taken from *Messages*):
bar.el changed on disk; really edit the buffer? (y, n, r or C-h) n
ask-user-about-supersession-threat: File changed on disk: c:/foo/bar.el
I just reverted the buffer and continued. But I am positive that
nothing outside Emacs modified the file. I'm not even aware of
something running that could do that. I was editing and saving
occasionally - nothing more.
Anyway, hoping this helps in some way...

I've been seeing the same kind of prompts lately when editing files in
Emacs in Ubuntu inside a virtual machine.
IIRC all those files were were mounted from the host machine (MS Windows
7) using the vboxsf file system type.

Good to know that someone else is seeing something similar.
In my case, I'm using Windows XP and am not using vboxsf or anything else
special - just an ordinary laptop.

So, I can now reproduce it 100% in the conditions I mentioned above. And
it's mighty annoying.
0. Open a file.
1. Make some changes. Emacs complies.
2. Press C-x C-s, saved successfully.
3. Try to make a single modification. Emacs instantly prompts "...
changed on disk; really edit the buffer?".
Answer yes -> goto 4, answer no -> goto 3.
Answer "revert", buffer reverts, goto -> 1.
4. Make modifications, try to save: "... has changed since visited or
save. Save anyway?" Answer yes -> goto 2.
If auto-revert-mode is enabled, and you wait the required interval of
time after 2. without making modifications, the buffer is "reverted",
also goto -> 1.
All this on the latest trunk. A build from the latest emacs-24 doesn't
exhibit the problem. Same with not-exactly-latest builds from these
branches I had a few hours ago, with the possible exception of
auto-revert-mode, IIRC it was less reliably helpful. Not sure.
Any tips for debugging this?
I'm doing bzr bisect, but it will take a while.

Bisect points to revision 110875
(eggert@cs.ucla.edu-20121113013514-5dej3lndyeb2dwq3):
Fix a race with verify-visited-file-modtime.
Since at least 1991 Emacs has ignored an mtime difference of no
more than one second, but my guess is that this was to work around
file system bugs that were fixed long ago. Since the race is
causing problems now, let's remove that code.
* fileio.c (Fverify_visited_file_modtime): Do not accept a file
whose time stamp is off by no more than a second. Insist that the
file time stamps match exactly.
Paul, any suggestions?

Therefore, I doubt that the same problem was the root cause of the
problem on Drew's laptop.

I'm not Paul, but can't you synchronize the clocks of the two
machines?

I'd guess it's a filesystem problem, where a file's
timestamp spontaneously changes even though the file
itself has not changed. I had thought those bugs
fixed long ago, but maybe not.
Could you please start by trying the attached patch,
and then see what gets sent to stderr around the time
of the problem? That might help us work around the
problem better than the old code did (it introduced
some race conditions).

My uninformed guess was there's a delay when writing to the file, and so
the mtime is slightly later than the time Emacs saved.

It hard for me to say, but the symptoms are similar, and the timing
matches. I think this commit is the likely culprit, although the fix may
have to be slightly different in Drew's case. Or would be, if we could
reproduce it.

To the nanosecond? I'm not sure if I can.
But if what you're implying is right, I think rewinding the clock on the
host machine would also help. It doesn't.

That looks like a file system bug, I'm afraid.
Does the following work around the bug, if you
set the variable sloppy-file-time-stamps?

Not entirely.
When the value is t, it works ok right after I open the file, and also
if I wait a second or more between save buffer commands.
If I repeat modify -> save cycle quickly enough, the problem is still
visible.

Can you send the stderr output for that,
where get_stat_mtime is modified as before?

The "cycle quickly enough" principle doesn't work now. It was "almost
always works fine with very few occasional failures" an hour ago, then I
rebooted, and now the fix seems to not do anything at all, even after a
few later reboots and "make bootstrap"s.
And yes, the patch is applied and sloppy-file-time-stamps is t.

It's strange all right: it indicates that time stamps
are spontaneously jumping by 2 or more seconds, which I
can't explain by any file system bugs that I can think of.
Maybe it's a new class of bugs, but we'd need to know more
about them.
Could you please try instrumenting via this patch instead?
It should help diagnosis. Thanks.

You're evidently getting different behavior, since you don't see
lread.c at all, for example. If I'm guessing right, I think the key
sequence in your transcript is here:
fileio.c:5359: stat_mtime=1358287604.023708900
fileio.c:5020: stat_mtime=1358287610.000000000

fileio.c:5359: stat_mtime=1358287613.927966600
and that this corresponds to the last 5 lines of my transcript.
What happens if you apply the following patch as well?
Does it cause Emacs to output "fstat and lstat disagree!"?

So, this is definitely new behavior, I checked the emacs-24 build, and
it now also exhibits the problem (it didn't previously), so this stuff
is not caused by the 2-months-old commit of yours.
Maybe it's a sign of my system slowly falling apart. I'm going to test
this on a different virtual machine.

It does sound like a fairly serious issue of some sort.
I did think of a patch (attached) but I'd rather not
apply it if the system in question is merely experimental,
since it introduces a race even on non-buggy systems.

I've been using the virtual machine to code Ruby for some time now, and
I intend to continue doing it. It is replaceable, though, since all the
important stuff is backed up.
Thank you for the patch, it works perfectly on the file mounted over
vboxsf (but regarding applying it, see (*)).
I just now recompiled emacs-24 (revno 111176) again (bzr revert; make
clean; make bootstrap) on the Ubuntu machine, and it seems to work fine
now. Also recompiled the trunk a few times. The "sloppy" patch now works
fine as well, aside from the need to explicitly set the variable. "fstat
and lstat mismatch" is still there, though, so it's probably unrelated.
No idea what the problem was with my tests last time, I'm blaming space
rays.
Looked at the VirtualBox bug reports, found just this one:
https://www.virtualbox.org/ticket/10986, not much information there.
Some more about space rays:
1) I now have a version of Emacs compiled on a brand-new Fedora virtual
machine from emacs-24 branch (revno 111185) that exhibits the problem.
Just tested it simultaneously with Ubuntu, emacs-24 on Fedora is buggy,
Ubuntu's is not. The following items (2 and 3) are from a few hours ago,
when I tested Fedora machine exclusively.
2) Editing the file on a different disk on the host system (HDD vs SSD)
makes no difference, the bug is present.
3) Process Monitor doesn't show any other processes accessing the file
on the host machine other than VirtualBox.exe, SYSTEM and
SearchProtocolHost.exe. The last one goes away if I stop the Windows
Search service, but the problem stays. I'm attaching the exported event
log for the open-modify-save scenario (file-access-log.csv) in case
someone knowledgeable can see anything weird there (Eli?).
(*) I tried to work around the whole thing by instead sharing the
directory in Windows the usual way and mounting it over CIFS (the
package cifs-utils in Ubuntu). Yet again, emacs-24 works fine as-is (on
both virtual machines, in this use case), but the trunk (revno 111517)
exhibits the same buggy behavior I've been writing about.
And the "sloppy" patch helps (when the var is set), but the last one
doesn't. See the instrumented output for the usual scenario with the
last patch applied, below.
Can anyone confirm this? Mounting stuff over CIFS/Samba should be a
relatively common situation.
If this is indeed reproducible, I think we need this to work without
requiring the user to customize a variable.

I suspect that what you see is some bad interaction between VirtualBox
and the nasty way Windows disk cache optimizes its disk I/O. It is
known to update the file attributes lazily, so data could be written
to a file without the file's directory entry updated at the same time,
until some time later.

I don't see anything interesting there, although I cannot pretend that
I've studied every single entry.

Just wanted to say that I see the same issue in a VirtualBox VM running
Ubuntu 12.04 in a Windows 7 host after I upgraded to the latest Emacs
pretest (from a version somewhere around shortly before the first
one). It's difficult to reproduce, so I'm afraid bisecting the offending
commit is not feasible. It happens maybe once an hour, but then several
times in a row.

I agree. But I would rather avoid having Emacs assume
that file system time stamps can be off by several seconds,
since that'll cause Emacs to miss changes that it should report.
Does the following patch help? It should be applied anyway,
since it closes a minor race even on non-buggy file systems.
I'm hoping that it helps to work around your bug by using
fstat both times, instead of fstat in one place and stat
in another, since the file system bug seems to be that
fstat and stat disagree.

The first time stamp comes from lstat, the second
from stat. If the file is actually on an NTFS file
system from the underlying host, the first time stamp
cannot possibly be right, since these file systems
have a time stamp resolution of 100 nanoseconds.
The second time stamp would be the correct one.
So it does seem to be a file system bug. Is this something
that you can reproduce with a little C program, that
creates a file, and invoke lstat and stat on it?
What happens when you run the following program
in your file system? It should output time stamps
that are identical. You may need to substitute
something else (like sleep (10)) for "sync ()"
to trigger the bug.
#include <fcntl.h>
#include <sys/stat.h>
#include <stdio.h>
#include <unistd.h>
int
main (void)
{
char const *file = "foo";
struct stat lst, st;
int fd;
unlink (file);
fd = open (file, O_CREAT | O_WRONLY, -1);
if (fd < 0)
return perror ("open"), 1;
if (lstat (file, &lst) != 0)
return perror ("lstat"), 1;
sync ();
if (stat (file, &st) != 0)
return perror ("stat"), 1;
printf ("%ld.%09ld\n", (long) lst.st_mtim.tv_sec, lst.st_mtim.tv_nsec);
printf ("%ld.%09ld\n", (long) st.st_mtim.tv_sec, st.st_mtim.tv_nsec);
return 0;
}

I wonder why I don't see that with the straight Windows build editing
files on the local filesystem. Does it forcibly disable some optimizations?

Oh well. It was worth a try.

It is on NTFS, but we're separated from it by at least CIFS server and
client implementations.

The time stamps were identical in all combinations:
1) Local VM filesystem (ext4).
2) vboxsf.
3) cifs.
a) sync ();
b) sleep (10);
c) sleep (0.1);
Maybe the bug is only triggered when we're editing an existing file?

I'd like to report that after shutdown, reboot and whatever, my
yesterday's build of emacs-24 on Ubuntu is again buggy on vboxsf. But it
still works fine in the cifs-mounted folder, so if all else fails, I
guess we can still revert the commit I mentioned previously and
recommend people to avoid vboxsf. Maybe then change that code
piece-by-piece to see what causes the breakage.

Alas, no dice. It didn't help neither with vboxsf, nor with cifs.

Nope, only on ext4.

vboxsf:
1358485717.265985900 fstat
1358485717.265985900 lstat
1358485717.265985900 stat

cifs:
1358485764.638001400 fstat
1358485764.638001400 lstat
1358485764.638001400 stat

1358485764.638001400 lstat
1358485764.638001400 stat
ext4 (just for completeness):
1358485649.211315918 fstat
1358485649.211315918 lstat
1358485649.211315918 stat

1358485649.223315921 lstat
1358485649.223315921 stat
Ran it quite a few times, the results were always identical.

That looks busted, since there's
a 10 ms sleep followed by a write at the two
points I marked "*" above, which means that
fstat, lstat, and stat are all wrong after the "*".
There's a similar problem with your vboxsf output.
ext4 looks OK.
I see that there is a known bug about Samba and 'write'
and st_mtime; see <https://bugzilla.samba.org/show_bug.cgi?id=6925>.
Could this be the bug you're running into, with cifs?
If you change the sleep to 100 ms, does that fix
the above behavior? How about 1 second? 2 seconds?

Too bad. Oh well, it's a change that should be made anyway,
so I installed it as trunk bzr 111546. I'll look into the
main problem a bit more.

Two points? I see one asterisk. Otherwise, yes, looks like a problem.

Maybe it is, I don't know. The bug describes a Linux server and says
that the Windows client is also having the problem. I just mounted the
shared folder on the same machine as a different disk, and the native
Emacs trunk build doesn't seem to trigger the bug.

Nope, not even 10 or 60 seconds. The pause is visible, but the numbers
are the same.

I'd like to add that when I open a file on cifs in a emacs-24 Emacs
build, and then do "touch <filename>" in the console on the server (host
machine), Emacs still reliably detects the change.
If I do nothing, and auto-revert-mode is on, it will revert it in a few
seconds. If I "touch" and then quickly switch to the Emacs in the VM and
try to make a change, it also says "file changed, really edit?"

This is speculation, but I presume that locally the file-I/O API calls
interact with the cached files better than what VirtualBox's Posix
emulation does.
Or maybe I'm wrong, and we will start seeing similar problems on
Windows, now that Emacs uses 'fstat' much more than it did a year or
so ago (when 'fstat' was not used in the native Windows build at all).

Who said anything was actually written to the file? You'd need
'fsync' to be sure, don't you?

A small wonder, since nothing is written to the file in this test
proggy, unlike in the original scenario.

Sticking fsync(fd) after the call to 'write' doesn't change anything.
If, however, I move the 'nanosleep' after the 'write' and set the
interval to 1 or 2 seconds, on vboxsf the numbers often become
different, but without guarantee. With 1 second, they usually the same,
with 2 second, they're mostly different, but still the same sometimes.

Adding another 'nanosleep' before the 'write' doesn't change that.
On cifs, the numbers are never different.

That depends on what one means by "actually written". :-)
POSIX says a 'write' must result in st_mtime being updated
some time before the file's time stamp is used (and 'fstat'
and 'stat' both count as uses). It is not required that the
written data or the updated st_mtime physically be stored on
nonvolatile storage; if the system crashes, the updates might
get lost.]
Also, it's not required that st_mtime must be updated to the
exact time stamp of the write -- it can be updated to a later
time stamp, so long as the later time stamp comes before st_mtime's
first use. But the point is that st_mtime must be updated
"in memory", so to speak, just as the file's data must get
updated "in memory", so that any uses of the file see the
new st_mtime and the new data that got written.
Here, we seem to have some cases where a write can occur
but st_mtime is not updated before the next stat or fstat.
I don't yet know how to characterize these cases, or how to
work around them. Even Emacs's old approach (allow up to
1 second of slop) seems like it won't work in some cases
that have been reported here: over 2 seconds of slop in
<http://bugs.gnu.org/13149#115>, and over one minute of
slop in <http://bugs.gnu.org/13149##100>!
One approach that I've been toying with is that
Emacs could inspect the file system type, and if the file
system is known to be reliable (ext2, ufs, zfs, ...) we stick
with the new behavior in the trunk which uses fstat with no slop,
but otherwise we fall back on the Emacs-24 behavior, using stat
with 1 second of slop. This won't allow the instances of
longer-than-1-second slops that we've seen reported here,
but maybe that's good enough.
I'm not particularly happy with this idea, but there is
a limit to what Emacs can do to work around filesystem bugs.

Is is possible that the test is measuring something not directly
relevant? Like I mentioned, emacs-24 build seems to work fine on cifs in
all observable respects, but with this test, cifs has the slop of
infinity. Or close enough.

I suspect the problem is that cifs mishandles fstat
but works with stat/lstat. What does the following
program do for you?
#include <fcntl.h>
#include <sys/stat.h>
#include <stdio.h>
#include <unistd.h>
#include <time.h>
static int
report_times (int fd, char const *file)
{
struct stat fst, lst, st;
if (0 <= fd && fstat (fd, &fst) != 0)
return perror ("fstat"), -1;
if (lstat (file, &lst) != 0)
return perror ("lstat"), -1;
if (stat (file, &st) != 0)
return perror ("stat"), -1;
if (0 <= fd)
printf ("%ld.%09ld fstat\n", (long) fst.st_mtim.tv_sec, fst.st_mtim.tv_nsec);
printf ("%ld.%09ld lstat\n", (long) lst.st_mtim.tv_sec, lst.st_mtim.tv_nsec);
printf ("%ld.%09ld stat\n", (long) st.st_mtim.tv_sec, st.st_mtim.tv_nsec);
printf ("\n");
return 0;
}
int
main (void)
{
static char const file[] = "foo";
struct timespec interval;
int fd;
unlink (file);
fd = open (file, O_CREAT | O_WRONLY, -1);
if (fd < 0)
return perror ("open O_CREAT"), 1;
if (report_times (fd, file) != 0)
return 1;
interval.tv_sec = 0;
interval.tv_nsec = 10000000;
if (nanosleep (&interval, 0) != 0)
return perror ("nanosleep"), 1;
if (write (fd, file, sizeof file - 1) != sizeof file - 1)
return perror ("write"), 1;
if (report_times (fd, file) != 0)
return 1;
if (close (fd) != 0)
return perror ("close"), 1;
if (report_times (-1, file) != 0)
return 1;
fd = open (file, O_RDONLY, 0);
if (fd < 0)
return perror ("open O_RDONLY"), 1;
if (report_times (fd, file) != 0)
return 1;
return 0;
}
It should output something like this:
1358556859.329948949 fstat
1358556859.329948949 lstat
1358556859.329948949 stat
1358556859.341948950 fstat
1358556859.341948950 lstat
1358556859.341948950 stat
1358556859.341948950 lstat
1358556859.341948950 stat
1358556859.341948950 fstat
1358556859.341948950 lstat
1358556859.341948950 stat
That is, the first batch of times should differ from the other
batches, all of which should be the same.

cifs:
1358557459.946082000 fstat
1358557459.946082000 lstat
1358557459.946082000 stat

1358557459.958583600 fstat
1358557459.958583600 lstat
1358557459.958583600 stat
vboxsf:
1358557454.975950900 fstat
1358557454.975950900 lstat
1358557454.975950900 stat
1358557454.975950900 fstat
1358557454.975950900 lstat
1358557454.975950900 stat

1358557454.988952600 stat

1358557454.988952600 lstat
1358557454.988952600 stat
So, vboxsf sees the change after the file has been closed, cifs - when
it's reopened.

My goodness, I didn't realize CIFS was *that* buggy.
But this suggests a reason why the patch in
<http://bugs.gnu.org/13149#61> worked for vboxsf
and not CIFS, and even better it suggests a
variation that might work with CIFS too.
Could you please try the attached patch?

Ooooh yeah. It works. Thanks a lot! :)
I think I saw it fail once, right after I recompiled the patched
version, but after that it's been working fine, on both filesystems.
That means, better than the emacs-24 build, which started to go haywire
again on vboxsf. I even opened the same file in both at the same time,
and the patched trunk was the non-buggy one.
So I think it's good to install, but I can play with it for a few days
first, if you prefer.

Thanks for remembering me. ;-) Just kidding.
I'll be glad to keep an eye out. But I probably won't be able to help any more
with this. As you've seen, you have had to dig into it without me.
I only saw the problem once. And I have no idea what I was doing at the time or
whether it even mattered. Anyway, I'm glad you were able to learn something
about either the problem I saw or something similar. Let's hope it's taken care
of now. Thx.

Nope, this is still a problem - it just happened again, with a 2-day-old build.
I was editing a file, then had just saved it (C-x C-s) and tried to continue
editing, and I got the message saying that the file on disk had been changed and
asking me if I really wanted to edit the buffer.
IOW: I typed some chars, did C-x C-s, then tried to type some more chars. Boom.
Oh, and BTW, shouldn't the prompt/message saying that the file was changed and
asking me whether I wanted to edit be recorded in *Messages*? It is not. That
too seems like a bug, but I'll let you decide that.
This is with this build:

Wow, it just happened _again_, and I wasn't even doing anything in Emacs (and
certainly wasn't doing anything to the file outside Emacs).
I was reading mail (outside Emacs), then went back to Emacs and tried to type
some more in the buffer (which I know had been saved), and I got the same
message/prompt again.
HTH.

If that last message of mine confuses things, don't put too much stock in it.
There's a tiny possibility that after the first message/prompt I did not bother
to revert the buffer (I don't remember), so perhaps the second message/prompt
was just a repeat from the same Emacs state. Sorry, IOW, I can't be sure about
this second occurrence. HTH/thx.

Then it's a different problem. That one was solved on Jan 19.
What is the filesystem of that file? NTFS or FAT32?

Nope, this is the bug I filed. You fixed a different bug, perhaps. This one is

FAT32.

Debugging this needs running Emacs under a debugger or instrumenting
the functions involved with special code. So I guess we are waiting
for someone else to hit this and offer help.

I stared at the code a bit and found an unlikely bug
that would cause the reported symptoms. The bug occurs if the
first write-region to a buggy file system happens to be
an append that appends nothing. If this occurs, Emacs
incorrectly concludes that the file system is not buggy,
and later uses of write-region to that file system (assuming
no other non-buggy file systems are used in the meantime)
will behave in the bad way that Drew reported.
I installed a fix for this bug as trunk bzr 111656.
I'd be surprised if this fixes Drew's bug though.
Eli, does MS-Windows conform to POSIX by updating st_mtime when
Emacs creates a file (open with O_CREAT on a file that didn't
previous exist) or truncates a file (open with O_TRUNC
on a file that previously existed)?
For example, if Emacs uses O_TRUNC on a file that is already
empty, does MS-Windows update the file's time
stamp even though the file has not changed? If not,
that might explain the bug as well.
Drew, can you please try using the following hacky patch
for a while, and report what's in your *Messages* buffer
if you see the problem again?

No, sorry. I don't build Emacs. If there is a Lisp change I can test that, but
not a C change.

My crystal ball tells me that others will run into the same problem sooner or
later. AFAIK, I really don't do anything special that should affect this. But
my crystal ball has been wrong before.

MS-Windows doesn't conform to Posix, period ;-)
It's hard to say something definitive here, especially since some of
this depends on the filesystem being used (Drew uses FAT32, most
others use NTFS). I cannot find any documentation on this issue. The
only thing that Windows promises in its docs is that st_mtime is
updated when the last file descriptor for the file is closed. So the
time stamp might not be up to date by the time we look at it in
write-region, because we use 'fstat' there before closing the
descriptor we used for writing. However, the code that determines
valid_timestamp_file_system right after that should catch any problems
caused by this, and update the buffer's modtime to the value actually
recorded in the filesystem. Perhaps FAT32 (see below) should always
do this, i.e. we should disable the optimization of probing its time
stamp validity only once?

My testing indicates that a file on NTFS has its time stamp changed in
this scenario, while a file on FAT32 will not. (I used a USB flash
device for this testing, as I have no other volume accessible to me
that is formatted as FAT32.)
However, when the file is closed, the time stamp does get updated on
FAT32 as well. So the code which determines
valid_timestamp_file_system should have caught this as well. And
anyway, Drew's use case involves a non-empty file, so this precise
scenario is not a problem there. For a non-empty file, when it is
truncated by opening it with O_TRUNC, the file's size reflects
truncation on both NTFS and FAT32, at least on my XP system.

I certainly hope so. I tried to reproduce this using a USB flash
device, but couldn't.

Can you describe the file where this happened and any customizations
that could have made it stand out? What major mode was active there?
any hooks related to saving that could matter?
Also, does it happen always with this file, or very rarely?

Yes, definitely.
I would also install something similar in verify-visited-file-modtime,
so that next time it happens we could see how different are the time
stamps.
Thanks.

I have noticed the bug only a few times, as I said.
The file was an ordinary Emacs Lisp file, in Emacs Lisp mode. I don't recall
which file. I'm not aware of using any saving hooks.

OK, thanks, then we need to check for that problem too.
Rather than go through a lengthy remote debugging session
with Drew, I'm inclined to disable the heuristic
on MS-Windows, as that should fix the problem once
and for all. That is, we just live with the race conditions
on MS-Windows (which is what Emacs users have done for many years)
and fix the race conditions only on GNU and other systems
that support POSIX.1-2008 well.
I installed the following patch to try to do that, as trunk
bzr 111664. If Drew continues to have the problem even with
this patch, we can investigate further by inserting some
logging code along the lines that we discussed.

Now that 24.3 windows binaries have been released I observe exactly the
same problem on my XP box. I don't know how to reproduce it 100%. It
happens sporadically, but it happens. And yes, my user files are on a
FAT32 partition.
Is there a fix for it, e.g. some customization? Should I avoid FAT32? Or
do we have to live with it?

The fix for this bug is in the trunk, it didn't make it into Emacs
24.3. So I don't think you can do anything to avoid these annoyances,
especially since you don't build your Emacs (if you did, I could
perhaps show you how to work around that by a simple source change).

I can only say that I never saw this on NTFS filesystems that I use
every day with Emacs 24.3. (Why do you use FAT32, btw? it's so much
worse than NTFS.)

You're right. I'll consider to migrate everything to NTFS.
The reason why I still prefered FAT32 was that I used to backup some
directory trees by sync-ing them against FTP servers. NTFS volumes were
out of sync whenever we changed to daylight-saving time and back because
windows returns a modified timestamp on NTFS volumes, while FTP doesn't.
I avoided these annoyances stolidly keeping at FAT32.

There's a long thread in this bug report, but I think the conclusion is
that this was fixed on the trunk?

I can't speak to that. But I reported the bug when I was using
FAT32, and I no longer have that, FWIW. (I also have not noticed
the bug in a while, probably not since I switched from FAT32.)

IMO, yes.
