Subject: [PATCH 4/4] xfs: hook live rmap operations during a repair operation
Date: Fri, 30 Dec 2022 14:13:30 -0800	[thread overview]
Message-ID: <167243841061.696748.8124096499529531254.stgit@magnolia> (raw)
In-Reply-To: <167243840997.696748.11741067698987523110.stgit@magnolia>

From: Darrick J. Wong <djwong@kernel.org>

Hook the regular rmap code when an rmapbt repair operation is running so
that we can unlock the AGF buffer to scan the filesystem and keep the
in-memory btree up to date during the scan.

Signed-off-by: Darrick J. Wong <djwong@kernel.org>
