Subject: [PATCH v10 16/25] xfs: Add helper function xfs_attr_leaf_mark_incomplete
Date: Thu, 25 Jun 2020 16:30:09 -0700	[thread overview]
Message-ID: <20200625233018.14585-17-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200625233018.14585-1-allison.henderson@oracle.com>

This patch helps to simplify xfs_attr_node_removename by modularizing
the code around the transactions into helper functions.  This will make
the function easier to follow when we introduce delayed attributes.
