Subject: [PATCH] xfs: don't run inodegc flushes when inodegc is not active
Date: Wed, 4 Aug 2021 20:46:16 +1000 [thread overview]
Message-ID: <20210804104616.GL2757197@dread.disaster.area> (raw)
In-Reply-To: <20210804032030.GT3601443@magnolia>
From: Dave Chinner <dchinner@redhat.com>
A flush trigger on a frozen filesystem (e.g. from statfs)
will run queued inactivations and assert fail like this:
XFS: Assertion failed: mp->m_super->s_writers.frozen < SB_FREEZE_FS, file: fs/xfs/xfs_icache.c, line: 1861
Bug exposed by xfs/011.
Signed-off-by: Dave Chinner <dchinner@redhat.com>
