Subject: [PATCH 4/6] xfs: add a XFS_CORRUPT_ON macro
Date: Sun, 03 Nov 2019 14:24:30 -0800 [thread overview]
Message-ID: <157281987010.4151907.6435110079992395504.stgit@magnolia> (raw)
In-Reply-To: <157281984457.4151907.11281776450827989936.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Add a new macro, XFS_CORRUPT_ON, which we will use to integrate some
corruption reporting when the corruption test expression is true. This
will be used in the next patch to remove the ugly XFS_WANT_CORRUPT*
macros.
