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@xxxxxxxxxx> Reviewed-by: Darrick J.
