Subject: [PATCH v14 11/14] xfsprogs: Remove unused xfs_attr_*_args
Date: Fri, 18 Dec 2020 00:25:52 -0700 [thread overview]
Message-ID: <20201218072555.16694-12-allison.henderson@oracle.com> (raw)
In-Reply-To: <20201218072555.16694-1-allison.henderson@oracle.com>
Remove xfs_attr_set_args, xfs_attr_remove_args, and xfs_attr_trans_roll.
These high level loops are now driven by the delayed operations code,
and can be removed.
Additionally collapse in the leaf_bp parameter of xfs_attr_set_iter
since we only have one caller that passes dac->leaf_bp
Signed-off-by: Allison Henderson <allison.henderson@oracle.com>
