| Subject | [PATCH 17/45] xfs: use bio op accessors |
| Date | 2016-06-05 21:50 +0200 |

From: Mike Christie <mchristi@redhat.com>
Separate the op from the rq_flag_bits and have xfs
set/get the bio using bio_set_op_attrs/bio_op.
Signed-off-by: Mike Christie <mchristi@redhat.com>

v8:
1. Handled changes due to rebase and dropped signed offs due to
upstream changes since last review.
