Subject: [PATCH v12 10/32] xfsprogs: Refactor xfs_attr_rmtval_remove
Date: Wed, 26 Aug 2020 17:28:34 -0700 [thread overview]
Message-ID: <20200827002856.1131-11-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200827002856.1131-1-allison.henderson@oracle.com>
Refactor xfs_attr_rmtval_remove to add helper function
__xfs_attr_rmtval_remove. We will use this later when we introduce
delayed attributes. This function will eventually replace
xfs_attr_rmtval_remove
