swim3: mark swim3_init() static

2023-08-10T14:32:59+00:00

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

2023-06-13T15:45:40+00:00

Add back the accidentally dropped mode parameter. Fixes: b60f7635788a ("swim3: fix the floppy_locked_ioctl prototype") Reported-by: Randy Dunlap Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20230613154309.327557-1-hch@lst.de Signed-off-by: Jens Axboe

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

2023-06-12T14:04:05+00:00

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

2023-06-12T14:04:04+00:00

The mode argument to the ->release block_device_operation is never used, so remove it. Signed-off-by: Christoph Hellwig Reviewed-by: Hannes Reinecke Acked-by: Christian Brauner Acked-by: Jack Wang [rnbd] Link: https://lore.kernel.org/r/20230608110258.189493-10-hch@lst.de Signed-off-by: Jens Axboe

block: pass a gendisk to ->open

2023-06-12T14:04:04+00:00

->open is only called on the whole device. Make that explicit by passing a gendisk instead of the block_device.

block: pass a gendisk on bdev_check_media_change

2023-06-12T14:04:03+00:00

bdev_check_media_change should only ever be called for the whole device. Pass a gendisk to make that explicit and rename the function to disk_check_media_change.

block: remove blk_cleanup_disk

blk_cleanup_disk is nothing but a trivial wrapper for put_disk now, so remove it. Signed-off-by: Christoph Hellwig Reviewed-by: Hannes Reinecke Link: https://lore.kernel.org/r/20220619060552.1850436-7-hch@lst.de Signed-off-by: Jens Axboe

block: remove GENHD_FL_EXT_DEVT

2021-11-29T13:38:35+00:00

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

2021-10-18T20:42:44+00:00

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.

block/swim3: add error handling support for add_disk()

2021-10-18T20:41:37+00:00

We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. Signed-off-by: Luis Chamberlain Link: https://lore.kernel.org/r/20210927220302.1073499-2-mcgrof@kernel.org Signed-off-by: Jens Axboe
