Subject: [PATCH 8/8] xfs: dump corrupt recovered log intent items to dmesg consistently
Date: Wed, 26 Oct 2022 13:08:17 -0700	[thread overview]
Message-ID: <166681489778.3447519.2620356479140584610.stgit@magnolia> (raw)
In-Reply-To: <166681485271.3447519.6520343630713202644.stgit@magnolia>

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

If log recovery decides that an intent item is corrupt and wants to
abort the mount, capture a hexdump of the corrupt log item in the kernel
log for further analysis.  Some of the log item code already did this,
so we're fixing the rest to do it consistently.
