move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

auto-generated by the following:

for i in `git grep -l -w asm/unaligned.h`; do
	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done
for i in `git grep -l -w asm-generic/unaligned.h`; do
	sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i
done
git mv include/asm-generic/unaligned.h include/linux/unaligned.h
git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h
sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild

sr: convert to the atomic queue limits API

2024-06-14T16:19:44+00:00

Assign all queue limits through a local queue_limits variable and
queue_limits_commit_update so that we can't race updating them from
multiple places, and free the queue when updating them so that
in-progress I/O submissions don't see half-updated limits.

Also use the chance to clean up variable names to standard ones.

scsi: sr: Drop driver owner initialization

2024-04-06T00:58:25+00:00

Core in scsi_register_driver() already sets the .owner, so driver does not
need to.

scsi: sr: Have midlayer retry get_sectorsize() errors

2024-01-30T02:20:54+00:00

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_events

2023-10-13T20:36:20+00:00

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.

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

2023-06-30T18:57:07+00:00

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (ufs, pm80xx, libata-scsi, smartpqi,
  lpfc, qla2xxx).

  We have a couple of major core changes impacting other systems:

   - Command Duration Limits, which spills into block and ATA

   - block level Persistent Reservation Operations, which touches block,
     nvme, target and dm

  Both of these are added with merge commits containing a cover letter
  explaining what's going on"

block: replace fmode_t with a block-specific type for block open flags

2023-06-12T14:04:05+00:00

The only overlap between the block open flags mapped into the fmode_t and
other uses of fmode_t are FMODE_READ and FMODE_WRITE.  Define a new
blk_mode_t instead for use in blkdev_get_by_{dev,path}, ->open and
->ioctl and stop abusing fmode_t.

scsi: replace the fmode_t argument to scsi_ioctl with a simple bool

2023-06-12T14:04:04+00:00

Instead of passing a fmode_t and only checking it for FMODE_WRITE, pass
a bool open_for_write to prepare for callers that won't have the fmode_t.

->open is only called on the whole device.  Make that explicit by
