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> --- fs/xfs/libxfs/xfs_attr.c | 96 ++--------------------------------------- fs/xfs/libxfs/xfs_attr.h | 10 ++--- fs/xfs/libxfs/xfs_attr_remote.c | 1 - fs/xfs/xfs_attr_item.c | 8 ++-- 4 files changed, 9 insertions(+), 106 deletions(-) diff --git a/fs/xfs/libxfs/xfs_attr.c b/fs/xfs/libxfs/xfs_attr.c index 85b63bb..6e5a900 100644 --- a/fs/xfs/libxfs/xfs_attr.c +++ b/fs/xfs/libxfs/xfs_attr.c @@ -268,60 +268,6 @@ xfs_attr_set_shortform( } /* - * Checks to see if a delayed attribute transaction should be rolled.
