Subject: [PATCH v3 11/19] xfs: Factor out xfs_attr_rmtval_invalidate
Date: Thu, 5 Sep 2019 15:18:29 -0700 [thread overview]
Message-ID: <20190905221837.17388-12-allison.henderson@oracle.com> (raw)
In-Reply-To: <20190905221837.17388-1-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.
