Subject: rename ->make_request_fn and move it to the block_device_operations v2
Date: Wed, 1 Jul 2020 10:59:27 +0200 [thread overview]
Message-ID: <20200701085947.3354405-1-hch@lst.de> (raw)
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
