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

2022-01-14T13:37:34+00:00

Pull SCSI updates from James Bottomley:
 "This series consists of the usual driver updates (ufs, pm80xx, lpfc,
  mpi3mr, mpt3sas, hisi_sas, libsas) and minor updates and bug fixes.

  The most impactful change is likely the switch from GFP_DMA to
  GFP_KERNEL in a bunch of drivers, but even that shouldn't affect too
  many people"

scsi: ch: Don't use GFP_DMA

2021-12-23T04:40:02+00:00

The allocated buffers are used as a command payload, for which the block
layer and/or DMA API do the proper bounce buffering if needed.

scsi: remove the gendisk argument to scsi_ioctl

2021-11-29T13:41:29+00:00

Now that blk_execute_rq does not take a gendisk argument there is no need
to pass it through the scsi_ioctl callchain either.

scsi: scsi_ioctl: Call scsi_cmd_ioctl() from scsi_ioctl()

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

Ensure SCSI ULD only has to call a single ioctl helper.  This also adds a
bunch of missing ioctls to the ch driver, and removes the need for a
duplicate implementation of SCSI_IOCTL_SEND_COMMAND command.

scsi: core: Kill DRIVER_SENSE

2021-06-01T02:48:21+00:00

Replace the check for DRIVER_SENSE with a check for
scsi_status_is_check_condition().

Audit all callsites to ensure the SAM status is set correctly. For
backwards compability move the DRIVER_SENSE definition to sg.h, and update
sg, bsg, and scsi_ioctl to set the DRIVER_SENSE driver_status whenever
SAM_STAT_CHECK_CONDITION is present.

fix

scsi: core: Stop using DRIVER_ERROR

2021-06-01T02:48:21+00:00

Return the actual error code in __scsi_execute() (which, according to the
documentation, should have happened anyway).  And audit all callers to cope
with negative return values from __scsi_execute() and friends.

treewide: remove editor modelines and cruft

2021-05-07T07:26:34+00:00

The section "19) Editor modelines and other cruft" in
Documentation/process/coding-style.rst clearly says, "Do not include any
of these in source files."

I recently receive a patch to explicitly add a new one.

Let's do treewide cleanups, otherwise some people follow the existing code
and attempt to upstream their favoriate editor setups.

It is even nicer if scripts/checkpatch.pl can check it.

If we like to impose coding style in an editor-independent manner, I think
editorconfig (patch [1]) is a saner solution.
