Subject: [PATCH 10/10] xfs: trace log intent item recovery failures
Date: Thu, 03 Dec 2020 17:12:37 -0800 [thread overview]
Message-ID: <160704435695.734470.320027217185016602.stgit@magnolia> (raw)
In-Reply-To: <160704429410.734470.15640089119078502938.stgit@magnolia>
From: Darrick J. Wong <darrick.wong@oracle.com>
Add a trace point so that we can capture when a recovered log intent
item fails to recover.
