block: pass a queue_limits argument to blk_mq_alloc_disk

2024-02-13T15:56:59Z

Pass a queue_limits to blk_mq_alloc_disk and apply it if non-NULL. This will allow allocating queues with valid queue limits instead of setting the values one at a time later.

swim3: mark swim3_init() static

2023-08-10T14:32:59Z

This is the module init function, which by definition is used only locally, so mark it static to avoid a warning: drivers/block/swim3.c:1280:5: error: no previous prototype for 'swim3_init' [-Werror=missing-prototypes] Reviewed-by: Jack Wang Signed-off-by: Arnd Bergmann Signed-off-by: Jens Axboe

swim3: fix the floppy_locked_ioctl prototype

block: replace fmode_t with a block-specific type for block open flags

2023-06-12T14:04:05Z

The only overlap between the block open flags mapped into the fmode_t and other uses of fmode_t are FMODE_READ and FMODE_WRITE. Define a new blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and ->ioctl and stop abusing fmode_t.

block: remove the unused mode argument to ->release

block: remove GENHD_FL_EXT_DEVT

2021-11-29T13:38:35Z

All modern drivers can support extra partitions using the extended dev_t. In fact except for the ioctl method drivers never even see partitions in normal operation. So remove the GENHD_FL_EXT_DEVT and allow extra partitions for all block devices that do support partitions, and require those that do not support partitions to explicit disallow them using GENHD_FL_NO_PART.

swim3: add missing major.h include

2021-10-18T20:42:44Z

swim3 got this through blkdev.h previously, but blkdev.h is not including it anymore. Include it specifically for the driver, otherwise FLOPPY_MAJOR is undefined and breaks the compile on PPC if swim3 is configured.
