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.

Looks good to me, and it's a nice cleanup as well. Applied.

Dropped, insta-crashes with dm:

Hmm.  Can you send me what is at "submit_bio_noacct+0x1f6" from gdb?
Or your .config?

I'd have to apply and compile again. But it's a bad RIP, so I'm guessing
it's ->submit_bio == NULL. Let me know if you really need it, and I can
re-generate the OOPS and have the vmlinux too.
