Subject: [PATCH v8 15/20] xfs: Add remote block helper functions
Date: Fri, 3 Apr 2020 15:12:24 -0700 [thread overview]
Message-ID: <20200403221229.4995-16-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200403221229.4995-1-allison.henderson@oracle.com>
This patch adds two new helper functions xfs_attr_store_rmt_blk and
xfs_attr_restore_rmt_blk. These two helpers assist to remove redundant
code associated with storing and retrieving remote blocks during the
attr set operations.
