[v2,11/18] xfsprogs: Remove unused xfs_attr_*_args

Commit Message

Allison Henderson May 20, 2022, 7 p.m. UTC

Source kernel commit: 73159fc27c6944ebe55e6652d6a1981d7cb3eb4a

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
