block: pass struct queue_limits to the bio splitting helpers

2022-08-03T03:08:53+00:00

Allow using the splitting helpers on just a queue_limits instead of
a full request_queue structure.  This will eventually allow file systems
or remapping drivers to split REQ_OP_ZONE_APPEND bios based on limits
calculated as the minimum common capabilities over multiple devices.

block: change the blk_queue_bounce calling convention

2022-08-02T23:22:54+00:00

The double indirect bio leads to somewhat suboptimal code generation.
Instead return the (original or split) bio, and make sure the
request_queue arguments to the lower level helpers is passed after the
bio to avoid constant reshuffling of the argument passing registers.

Also give it and the helpers used to implement it more descriptive names.

block: remove __blk_get_queue

2022-07-21T17:03:17+00:00

__blk_get_queue is only called by blk_get_queue, so merge the two.

block: Use enum req_op where appropriate

2022-07-14T18:14:30+00:00

Change the type of the arguments that are used to pass a REQ_OP_* value
from int or unsigned int into enum req_op to improve static type
checking.
