The following patches, made over Linus's tree but also apply over Martin's 6.2 branches, allow scsi_execute* users to control exactly which errors are retried, so we can reduce the sense/sshd handling they have to do. The patches allow scsi_execute* users to pass in an array of failures which they want retried and also specify how many times they want them retried. If we hit an error that the user did not specify then we drop down to the default behavior. This allows us to remove almost all the retry logic from scsi_execute* users. We currently cannot handle the cases where the callers check some state/sleep between retries. v5: - Fix spelling (made sure I ran checkpatch strict) - Drop SCMD_FAILURE_NONE - Rename SCMD_FAILURE_ANY - Fix media_not_present handling where it was being retried instead of failed. - Fix ILLEGAL_REQUEST handling in read_capacity_16 so it was not retried. - Fix coding style, spelling and and naming convention in kunit and added more tests to handle cases like the media_not_present one where we want to force failures instead of retries. - Drop cxlflash patch because it actually checked it's internal state before performing a retry which we currently do not support. v4: - Redefine cmd definitions if the cmd is touched. - Fix up coding style issues. - Use sam_status enum. - Move failures initialization to scsi_initialize_rq (also fixes KASAN error). - Add kunit test. - Add function comments. v3: - Use a for loop in scsi_check_passthrough - Fix result handling/testing. - Fix scsi_status_is_good handling. - make __scsi_exec_req take a const arg - Fix formatting in patch 24 v2: - Rename scsi_prep_sense - Change scsi_check_passthrough's loop and added some fixes - Modified scsi_execute* so it uses a struct to pass in args
