In the past, I was using EXT3 with CONFIG_EXT4_USE_FOR_EXT23, and there
were problems with OOM Killer.  That was fixed by switching to
CONFIG_EXT3_FS.

I’ve recently tried to compile several versions of Linux-libre.  I used
‘/proc/config.gz’ but changed the mentioned options.  Whenever I tried,
I was getting multiple warnings, “a variable is defined but is not used”
or something like that.  I can’t remember the last time when I
configured a kernel myself.  So I’m not sure whether such warnings are
tolerable or not.
