scsi: core: Fix the unit attention counter implementation

2025-10-22T01:09:36Z

scsi_decide_disposition() may call scsi_check_sense(). scsi_decide_disposition() calls are not serialized. Hence, counter updates by scsi_check_sense() must be serialized. Hence this patch that makes the counters updated by scsi_check_sense() atomic.

scsi: libsas: Add dev_parent_is_expander() helper

2025-08-19T02:08:30Z

Many libsas drivers check if the parent of the device is an expander. Create a helper that the libsas drivers will use in follow up commits.

scsi: switch ->bios_param() to passing gendisk

2025-08-13T06:59:28Z

Instances are passed struct block_device *bdev argument; the only thing it is used for (if it's used in the first place) is bdev->bd_disk. Might as well pass that in the first place... Reviewed-by: Martin K. Petersen Reviewed-by: Christoph Hellwig Acked-by: Jens Axboe Signed-off-by: Al Viro

scsi: switch scsi_bios_ptable() and scsi_partsize() to gendisk

2025-08-13T06:59:28Z

Both helpers are reading the partition table of the disk specified by block_device of some partition on it; result depends only upon the disk in question, so we might as well pass the struct gendisk instead.

scsi: libsas: Refactor dev_is_sata()

2025-07-25T13:03:56Z

Use a switch statement in dev_is_sata() to make the code more readable (and probably slightly better than a series of or conditions). Also have this inline function return a boolean instead of an integer. No functional changes.

Configurations with large numbers of FC rports per host instance are taking a very long time to complete all devloss work. Increase potential parallelism by using a per-rport devloss_work_q for dev_loss_work and fast_io_fail_work. Signed-off-by: Ewan D.
