Are you testing integration-4.4 from Chris repo?
Or 4.3-rc from mainline repo with my qgroup reserve patchset applied?
Although integration-4.4 already merged qgroup reserve patchset, but it's
causing some strange bug like over decrease data sinfo->bytes_may_use,
mainly in generic/127 testcase.
But if qgroup reserve patchset is rebased to integration-4.3 (I did all my
old tests based on that), no generic/127 problem at all.
Did I mismerge things?

Not sure yet.
But at least some patches in 4.3 is not in integration-4.4, like the
following patch:
btrfs: Avoid truncate tailing page if fallocate range doesn't exceed inode
size
Have you tried testing integration-4.4 merged with current Linus git?
-chris
Integration-4.4 merged with Linus' master also fails. :(
Current known working branches are all based on 4.3-integration(4.2-rc5):
https://github.com/adam900710/linux/tree/qgroup_reserve_good
Tried 4.3-rc5 and 4.3-rc7, all fails with kernel warning in generic/137.
And due to the huge difference, I'm afraid it won't take a short time to
find the root cause...
Thanks,
Qu
