Ooops, too late anyway for 1.4.0 (congrats for the dev team BTW)! 😁
I sent an alternative, more elaborated patch to #59746. Some notes:
- Both `mkswap` and `swapon` complain about swap files with holes, so I deemed
it redundant to add notes about that (and besides, it should be rare enough
when using the `dd`-based creation technique).
- `filefrag` does work on non-Ext2 filesystems (by falling back to an older
ioctl), one just needs to force the extents output (`-e`) and run it as root
in case the newer ioctl fails. I used that in the swap file example.
- Yeah, there's a specific swap file example now with instructions on how to
get the offset with `filefrag`.
I hope that the new patch is more complete and straightforward than the
previous one.
Thanks everyone for the extra info, cheers!
