* scsi: sr: Have midlayer retry get_sectorsize() errorsMike Christie2024-01-301-18/+20
| | | | | | | | | | | | | | | | | This has get_sectorsize() have the SCSI midlayer retry errors instead of driving them itself. There is one behavior change where we no longer retry when scsi_execute_cmd() returns < 0, but we should be ok. We don't need to retry for failures like the queue being removed, and for the case where there are no tags/reqs the block layer waits/retries for us. For possible memory allocation failures from blk_rq_map_kern() we use GFP_NOIO, so retrying will probably not help.

* scsi: sr: Fix sshdr use in sr_get_eventsMike Christie2023-10-131-1/+2
| | | | | | | | | | | | | | If scsi_execute_cmd returns < 0, it doesn't initialize the sshdr, so we shouldn't access the sshdr. If it returns 0, then the cmd executed successfully, so there is no need to check the sshdr. This has us access the sshdr when we get a return value > 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | GENHD_FL_CD marks a gendisk as a vaguely CD-ROM like device. Besides being used internally inside of sunvdc.c an xen-blkfront it is used by xen-blkback as a hint to claim a device exported to a guest is a CD-ROM like device. Just check for disk->cdi instead which is the right indicator for "real" CD-ROM or DVD drivers. This will miss the paravirtualized guest drivers, but those make little sense to report anyway.
