Subject: [PATCH] xfs: remove xfs_bmap_sanity_check()
Date: Wed, 25 Feb 2015 17:41:10 +1100 [thread overview]
Message-ID: <1424846470-7623-1-git-send-email-david@fromorbit.com> (raw)
From: Dave Chinner <dchinner@redhat.com>
This code is redundant now that we have verifiers that sanity check
the buffers as they are read from disk.
