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: move zone related fields to struct gendisk

2022-07-06T12:46:26+00:00

Move the zone related fields that are currently stored in
struct request_queue to struct gendisk as these are part of the highlevel
block layer API and are only used for non-passthrough I/O that requires
the gendisk.

block: call blk_queue_free_zone_bitmaps from disk_release

2022-07-06T12:46:25+00:00

The zone bitmaps are only used for non-passthrough I/O, so free them as
soon as the disk is released.

2022-06-29T14:36:46+00:00

Lift setting disk->ia_ranges from disk_register_independent_access_ranges
into disk_set_independent_access_ranges, and make the behavior the same
for the registered vs non-registered queue cases.

blk-mq: cleanup disk sysfs registration

2022-06-28T17:32:42+00:00

Pass a gendisk to the sysfs register/unregister functions and give
them descriptive names.  Also move the unregistration helper next
to the one doing the registration.

block: remove a superflous queue kobject reference

2022-06-28T17:32:42+00:00

kobject_add already adds a reference to the parent that is dropped
on deletion, so don't bother grabbing another one.

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.
