Subject: [PATCH v24 07/11] xfs: Remove unused xfs_attr_*_args
Date: Tue, 24 Aug 2021 15:44:30 -0700 [thread overview]
Message-ID: <20210824224434.968720-8-allison.henderson@oracle.com> (raw)
In-Reply-To: <20210824224434.968720-1-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
