Subject: [4.11-rc3 BUG] xfs/348 crashes debug kernel
Date: Mon, 20 Mar 2017 22:22:51 +0800 [thread overview]
Message-ID: <20170320142251.GP14226@eguan.usersys.redhat.com> (raw)
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@oracle.com>
Date: Wed Mar 15 00:24:25 2017 -0700
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
