Hi,
I noticed xfs/348 could crash xfs debug build starting from 4.11-rc3,
and test failed on non-debug build xfs, and the only xfs patch in -rc3
is 630a04e79, reverting it "fixed" the crash for me.
commit 630a04e79dd41ff746b545d4fc052e0abb836120
Author: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

xfs: verify inline directory data forks
I appended the console log of the crash and test failure diff at the end
of email. If you need more information please let me knwo.
Thanks,
Eryu
P.S. 1: console log of the crash
