[PATCH 33/42] block: convert rq_data_dir helper to use REQ_OPs

Show all headers | View raw

From: Mike Christie <mchristi@redhat.com>

The request->op field is now always setup up with a REQ_OP.
This patch has the rq_data_dir helper convert the operation
to a WRITE or READ direction based on that.
