Subject: [PATCH 3/3] xfs: online repair of realtime summaries
Date: Tue, 26 Mar 2024 18:58:34 -0700 [thread overview]
Message-ID: <171150381736.3217242.4323532338029040508.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <171150381678.3217242.16606238202905878098.stgit@frogsfrogsfrogs>
From: Darrick J. Wong <djwong@kernel.org>
Repair the realtime summary data by constructing a new rtsummary file in
the scrub temporary file, then atomically swapping the contents.
