Subject: rename ->make_request_fn and move it to the block_device_operations v2
Hi Jens,
this series moves the make_request_fn method into block_device_operations
with the much more descriptive ->submit_bio name. It then also gives
generic_make_request a more descriptive name, and further optimize the
path to issue to blk-mq, removing the need for the direct_make_request
bypass.
Changes since v1:
- fix a null pointer dereference when dispatching from bio to request
based drivers
- clean up a few more comments
