block: remove blk_cleanup_disk

2022-06-28T12:33:15+00:00

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 the ->rq_disk field in struct request

2021-11-29T13:41:29+00:00

Just use the disk attached to the request_queue instead. Signed-off-by: Christoph Hellwig Reviewed-by: Chaitanya Kulkarni Reviewed-by: Martin K. Petersen Link: https://lore.kernel.org/r/20211126121802.2090656-4-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.

pf: fix error codes in pf_init_unit()

2021-10-18T20:42:16+00:00

Return a negative error code instead of success on these error paths. Fixes: fb367e6baeb0 ("pf: cleanup initialization") Signed-off-by: Dan Carpenter Link: https://lore.kernel.org/r/20211001122654.GB2283@kili Signed-off-by: Jens Axboe

pf: 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 Signed-off-by: Jens Axboe

pf: cleanup initialization

Refactor the pf initialization to have a dedicated helper to initialize a single disk. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

pf: use blk_mq_alloc_disk

Use the blk_mq_alloc_disk API to simplify the gendisk and request_queue allocation. Signed-off-by: Christoph Hellwig Reviewed-by: Chaitanya Kulkarni Link: https://lore.kernel.org/r/20210602065345.355274-7-hch@lst.de Signed-off-by: Jens Axboe

compat_ioctl: block: handle cdrom compat ioctl in non-cdrom drivers

2020-01-03T08:33:15+00:00

Various block drivers implement the CDROMMULTISESSION, CDROM_GET_CAPABILITY, and CDROMEJECT ioctl commands, relying on the block layer to handle compat_ioctl mode for them. Move this into the drivers directly as a preparation for simplifying the block layer later. When only integer arguments or no arguments are passed, the same handler can be used for .ioctl and .compat_ioctl, and when only pointer arguments are passed, the newly added blkdev_compat_ptr_ioctl can be used.
