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.

Hi Jens,

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
