We are hitting the following warning in the field pretty frequently on the

[11708.763067] WARNING: at fs/ext4/inode.c:363
ext4_da_update_reserve_space+0x261/0x280 [ext4]()
The issue was resolved via "ext4: fix warning in
ext4_da_update_reserve_space()" (7d7345322d60ed), but the fix was not
submitted as a stable update for 3.10. I was wondering if there's a reason
why this was not done, or if it was just overlooked?
The patch appears to have a dependency on "quota: provide interface for
readding allocated space into reserved space" (1c8924eb106c1ac), so I think
both would need to be submitted if you feel it's possible.
Have you tried backporting these two commits, and does it fix the
problem for you?
Yeah I backported both. They both apply cleanly to 3.10 iirc. I will
report back if they do not.
Yes, moving both of these to 3.10 fixes the problem for me.
I think it was mostly an oversight, although it might have also been
my thinking that it was only a warning, so it wasn't that critical to
backport. To be honest, I can't really recall exactly what happened
with that patch at this point.
If it does seen to work for you, I'm happy to suggest to the 3.10
stable kernel maintainers to have it be backported.
That would be great, thanks!
