Subject: [PATCH 10/17] xfs: log VLOOKUP xattr removal operations
Date: Thu, 16 Mar 2023 12:24:05 -0700 [thread overview]
Message-ID: <167899414496.15363.4226611011899994676.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <167899414339.15363.12404998880107296432.stgit@frogsfrogsfrogs>
From: Darrick J. Wong <djwong@kernel.org>
If high level code wants to do a deferred xattr remove operation with
the VLOOKUP flag set, we need to push this through the log.
