Subject: [PATCH] xfs: fix I_DONTCACHE
Date: Tue, 24 Aug 2021 12:32:08 +1000	[thread overview]
Message-ID: <20210824023208.392670-1-david@fromorbit.com> (raw)

From: Dave Chinner <dchinner@redhat.com>

Yup, the VFS hoist broke it, and nobody noticed. Bulkstat workloads
make it clear that it doesn't work as it should.

Fixes: dae2f8ed7992 ("fs: Lift XFS_IDONTCACHE to the VFS layer")
Signed-off-by: Dave Chinner <dchinner@redhat.com>
