Subject: [PATCH v6 07/16] xfs: Refactor xfs_attr_try_sf_addname
Date: Sat, 18 Jan 2020 15:50:26 -0700	[thread overview]
Message-ID: <20200118225035.19503-8-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200118225035.19503-1-allison.henderson@oracle.com>

To help pre-simplify xfs_attr_set_args, we need to hoist transacation
handling up, while modularizing the adjacent code down into helpers. In
this patch, hoist the commit in xfs_attr_try_sf_addname up into the
calling function, and also pull the attr list creation down.
