From 4e49ea4a3d276365bf7396c9b77b4d1d5923835a Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Sun, 5 Jun 2016 14:31:41 -0500 Subject: block/fs/drivers: remove rw argument from submit_bio This has callers of submit_bio/submit_bio_wait set the bio->bi_rw instead of passing it in. This makes that use the same as generic_make_request and how we set the other bio fields.
