block: move ->bio_split to the gendisk

2022-08-03T03:08:49+00:00

Only non-passthrough requests are split by the block layer and use the
->bio_split bio_set.  Move it from the request_queue to the gendisk.

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 the new blk_opf_t type

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

Use the new blk_opf_t type for arguments and variables that represent
request flags or a bitwise combination of a request operation and
request flags. Rename the function arguments and also a structure member
that hold a request operation and flags from 'rw' into 'opf'.

This patch does not change any functionality.

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.

block: Use try_cmpxchg in update_io_ticks

2022-07-12T20:39:06+00:00

Use try_cmpxchg instead of cmpxchg (*ptr, old, new) == old in
update_io_ticks. x86 CMPXCHG instruction returns success in ZF flag,
so this change saves a compare after cmpxchg (and related
move instruction in front of cmpxchg).

No functional change intended.

block: simplify disk shutdown

2022-06-28T12:30:26+00:00

Set the queue dying flag and call blk_mq_exit_queue from del_gendisk for
all disks that do not have separately allocated queues, and thus remove
the need to call blk_cleanup_queue for them.

Rename blk_cleanup_disk to blk_mq_destroy_queue to make it clear that
this function is intended only for separately allocated blk-mq queues.

This saves an extra queue freeze for devices without a separately
allocated queue.

block: stop setting the nomerges flags in blk_cleanup_queue

2022-06-28T12:30:26+00:00

These flags only apply to file system I/O, and all file system I/O is
already drained by del_gendisk and thus can't be in progress when
blk_cleanup_queue is called.
