block: handle bio_split_to_limits() NULL return

2023-01-18T10:48:58+00:00

commit 613b14884b8595e20b9fac4126bf627313827fbe upstream. This can't happen right now, but in preparation for allowing bio_split_to_limits() returning NULL if it ended the bio, check for it in all the callers. Signed-off-by: Jens Axboe Signed-off-by: Greg Kroah-Hartman

rsxx: convert to blk_alloc_disk/blk_cleanup_disk

2021-06-01T13:42:23+00:00

Convert the rsxx driver to use the blk_alloc_disk and blk_cleanup_disk helpers to simplify gendisk and request_queue allocation. Signed-off-by: Christoph Hellwig Reviewed-by: Ulf Hansson Link: https://lore.kernel.org/r/20210521055116.1053587-10-hch@lst.de Signed-off-by: Jens Axboe

block: store a block_device pointer in struct bio

2021-01-25T01:17:20+00:00

Replace the gendisk pointer in struct bio with a pointer to the newly improved struct block device. From that the gendisk can be trivially accessed with an extra indirection, but it also allows to directly look up all information related to partition remapping.

block: move ->make_request_fn to struct block_device_operations

2020-07-01T13:27:24+00:00

The make_request_fn is a little weird in that it sits directly in struct request_queue instead of an operation vector. Replace it with a block_device_operations method called submit_bio (which describes much better what it does). Also remove the request_queue argument to it, as the queue can be derived pretty trivially from the bio. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: remove the request_queue argument from blk_queue_split

2020-07-01T13:27:23+00:00

The queue can be trivially derived from the bio, so pass one less argument. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

rsxx: stop using ->queuedata

2020-07-01T13:27:23+00:00

Instead of setting up the queuedata as well just use one private data field. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

rsxx: use bio_{start,end}_io_acct

2020-05-27T11:21:23+00:00

Switch rsxx to use the nicer bio accounting helpers. Signed-off-by: Christoph Hellwig Reviewed-by: Konstantin Khlebnikov Signed-off-by: Jens Axboe

block: simplify queue allocation

2020-03-27T16:23:43+00:00

Current make_request based drivers use either blk_alloc_queue_node or blk_alloc_queue to allocate a queue, and then set up the make_request_fn function pointer and a few parameters using the blk_queue_make_request helper. Simplify this by passing the make_request pointer to blk_alloc_queue, and while at it merge the _node variant into the main helper by always passing a node_id, and remove the superfluous gfp_mask parameter. A lower-level __blk_alloc_queue is kept for the blk-mq case. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

block: genhd: add 'groups' argument to device_add_disk

2018-09-28T14:30:28+00:00

Update device_add_disk() to take an 'groups' argument so that individual drivers can register a device with additional sysfs attributes. This avoids race condition the driver would otherwise have if these groups were to be created with sysfs_add_groups().
