Subject: [PATCH 3/3] xfs_repair: add post-phase error injection points
Date: Fri, 12 Feb 2021 21:47:01 -0800 [thread overview]
Message-ID: <161319522176.422860.4620061453225202229.stgit@magnolia> (raw)
In-Reply-To: <161319520460.422860.10568013013578673175.stgit@magnolia>
From: Darrick J. Wong <djwong@kernel.org>
Create an error injection point so that we can simulate repair failing
after a certain phase.
