block: move GENHD_FL_BLOCK_EVENTS_ON_EXCL_WRITE to disk->event_flags

2023-09-19T10:23:02+00:00

[ Upstream commit 1545e0b419ba1d9b9bee4061d4826340afe6b0aa ]

GENHD_FL_BLOCK_EVENTS_ON_EXCL_WRITE is all about the event reporting
mechanism, so move it to the event_flags field.

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2021-09-02T22:09:46+00:00

Pull SCSI updates from James Bottomley:
 "This series consists of the usual driver updates (ufs, qla2xxx,
  target, smartpqi, lpfc, mpt3sas).

  The core change causing the most churn was replacing the command
  request field request with a macro, allowing us to offset map to it
  and remove the redundant field; the same was also done for the tag
  field.

  The most impactful change is the final removal of scsi_ioctl, which
  has been deprecated for over a decade"

pd: fix a NULL vs IS_ERR() check

2021-08-27T13:45:48+00:00

blk_mq_alloc_disk() returns error pointers, it doesn't return NULL
so correct the check.

Only the sr driver can handle SCSI passthrough requests, so move the call
to scsi_cmd_blk_ioctl() there.
