blk-integrity: register sysfs attributes on struct device

2024-10-17T13:11:33+00:00

Upstream commit ff53cd52d9bdbf4074d2bbe9b591729997780bd3.

The "integrity" kobject only acted as a holder for static sysfs entries.
It also was embedded into struct gendisk without managing it, violating
assumptions of the driver core.

Instead register the sysfs entries directly onto the struct device.

Also drop the now unused member integrity_kobj from struct gendisk.

block: rename GENHD_FL_NO_PART_SCAN to GENHD_FL_NO_PART

2023-09-19T10:23:02+00:00

[ Upstream commit 46e7eac647b34ed4106a8262f8bedbb90801fadd ]

The GENHD_FL_NO_PART_SCAN controls more than just partitions canning,
so rename it to GENHD_FL_NO_PART.

[ Upstream commit 1545e0b419ba1d9b9bee4061d4826340afe6b0aa ]

GENHD_FL_BLOCK_EVENTS_ON_EXCL_WRITE is all about the event reporting
mechanism, so move it to the event_flags field.

The flag to indicate an unlocked native capacity is dynamic state,
not a driver capability flag, so move it to disk->state.

Drop various include not actually used in genhd.h itself, and
move the remaning includes closer together.

block: drain file system I/O on del_gendisk

2021-10-16T03:02:50+00:00

Instead of delaying draining of file system I/O related items like the
blk-qos queues, the integrity read workqueue and timeouts only when the
request_queue is removed, do that when del_gendisk is called.  This is
important for SCSI where the upper level drivers that control the gendisk
are separate entities, and the disk can be freed much earlier than the
request_queue, or can even be unbound without tearing down the queue.

2021-08-23T18:55:45+00:00

Properly unwind on errors in device_add_disk.  This is the initial work
as drivers are not converted yet, which will follow in separate patches.

This was a leftover from the legacy alloc_disk interface.  Switch
