We are hitting the following warning in the field pretty frequently
on the latest 3.10 stable kernel:
[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.
Since the problem is relatively harmless, I think we didn't bother
porting it to 3.10. Feel free to port those two patches to 3.10 and submit
them to stable@xxxxxxxxxxxxxxx.
Thanks for the reply Jan.
I've ported them locally to 3.10 and they seem to apply cleanly
as-is. I can submit the request to stable as long as you believe
there's no harm in doing so, or any other dependency which may be
required. My testing of a patched 3.10 with the two above patches
shows the warning no longer triggers as you report in your commit
log.
I'm not aware of any reason why these patches shouldn't be in 3.10 stable
so just go ahead. Thanks!
It looks like there is a small merge conflict in one of the patches. I
will respin it and submit to stable cc'ing you guys.
Thanks
Josh
