scsi: scsi_ioctl: Move the "block layer" SCSI ioctl handling to drivers/scsi

2021-07-29T02:24:27+00:00

Merge the ioctl handling in block/scsi_ioctl.c into its only caller in
drivers/scsi/scsi_ioctl.c.

scsi: scsi_ioctl: Simplify SCSI passthrough permission checking

2021-07-29T02:24:26+00:00

Remove the separate command filter structure and just use a switch
statement (which also cought two duplicate commands), return a bool and
give the function a sensible name.

scsi: bsg: Decouple from scsi_cmd_ioctl()

2021-07-29T02:24:25+00:00

Decouple bsg from scsi_cmd_ioctl().  This requires a small amount of code
duplication, but will allow moving all SCSI ioctl handling into SCSI
midlayer.

scsi: block: Add a queue_max_bytes() helper

2021-07-29T02:24:25+00:00

Return the max_sectors value in bytes.  Lifted from scsi_ioctl.c.

scsi: scsi_ioctl: Remove scsi_verify_blk_ioctl()

2021-07-29T02:24:25+00:00

Manually verify that the device is not a partition and the caller has admin
privіleges at the beginning of the sr ioctl method and open code the
trivial check for sd as well.

Pull more block updates from Jens Axboe:
 "A combination of changes that ended up depending on both the driver
  and core branch (and/or the IDE removal), and a few late arriving
  fixes. In detail:

   - Fix io ticks wrap-around issue (Chunguang)

   - nvme-tcp sock locking fix (Maurizio)

   - s390-dasd fixes (Kees, Christoph)

   - blk_execute_rq polling support (Keith)

   - blk-cgroup RCU iteration fix (Yu)

   - nbd backend ID addition (Prasanna)

   - Partition deletion fix (Yufen)

   - Use blk_mq_alloc_disk for mmc, mtip32xx, ubd (Christoph)

   - Removal of now dead block request types due to IDE removal
     (Christoph)

   - Loop probing and control device cleanups (Christoph)

   - Device uevent fix (Christoph)

   - Misc cleanups/fixes (Tetsuo, Christoph)"

block: remove REQ_OP_SCSI_{IN,OUT}

2021-06-30T21:34:19+00:00

With the legacy IDE driver gone drivers now use either REQ_OP_DRV_*
or REQ_OP_SCSI_*, so unify the two concepts of passthrough requests
into a single one.
