Subject: [PATCH 3/3] xfs_repair: rebuild block mappings from rmapbt data
Date: Sun, 31 Dec 2023 14:08:17 -0800	[thread overview]
Message-ID: <170404990842.1793572.11558699389826458485.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <170404990800.1793572.4237173751599480312.stgit@frogsfrogsfrogs>

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

Use rmap records to rebuild corrupt inode forks instead of zapping
the whole inode if we think the rmap data is reasonably sane.
