Subject: [PATCH v7 11/20] xfsprogs: Factor out xfs_attr_rmtval_invalidate
Date: Sat, 22 Feb 2020 19:05:45 -0700	[thread overview]
Message-ID: <20200223020554.1731-12-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200223020554.1731-1-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.
