Subject: [PATCH v11 08/25] xfs: Factor out xfs_attr_rmtval_invalidate
Date: Mon, 20 Jul 2020 17:15:49 -0700 [thread overview]
Message-ID: <20200721001606.10781-9-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200721001606.10781-1-allison.henderson@oracle.com>
Because new delayed attribute routines cannot roll transactions, we
carve off the parts of xfs_attr_rmtval_remove that we can use. This
will help to reduce repetitive code later when we introduce delayed
attributes.
