scsi: switch ->bios_param() to passing gendisk

2025-08-13T06:59:28+00:00

Instances are passed struct block_device *bdev argument; the only thing
it is used for (if it's used in the first place) is bdev->bd_disk.
Might as well pass that in the first place...

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

2025-03-27T02:57:34+00:00

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (scsi_debug, ufs, lpfc, st, fnic, mpi3mr,
  mpt3sas) and the removal of cxlflash.

  The only non-trivial core change is an addition to unit attention
  handling to recognize UAs for power on/reset and new media so the tape
  driver can use it"

scsi: mptfusion: Mark device strings as nonstring

In preparation for memtostr*() checking that its source is marked as
nonstring, annotate the device strings accordingly.

scsi: usb: Rename the RESERVE and RELEASE constants

2025-02-13T03:20:55+00:00

The names RESERVE and RELEASE are not only used in  but
also elsewhere in the kernel:

$ git grep -nHE 'define[[:blank:]]*(RESERVE|RELEASE)[[:blank:]]'
drivers/input/joystick/walkera0701.c:13:#define RESERVE 20000
drivers/s390/char/tape_std.h:56:#define RELEASE			0xD4	/* 3420 NOP, 3480 REJECT */
drivers/s390/char/tape_std.h:58:#define RESERVE			0xF4	/* 3420 NOP, 3480 REJECT */

Additionally, while the names of the symbolic constants RESERVE_10 and
RELEASE_10 include the command length, the command length is not included
in the RESERVE and RELEASE names. Address both issues by renaming the
RESERVE and RELEASE constants into RESERVE_6 and RELEASE_6 respectively.

scsi: Convert SCSI drivers to .sdev_configure()

2024-12-04T20:34:28+00:00

The only difference between the .sdev_configure() and .slave_configure()
methods is that the former accepts an additional 'limits' argument.
Convert all SCSI drivers that define a .slave_configure() method to
.sdev_configure(). This patch prepares for removing the
.slave_configure() method. No functionality has been changed.

scsi: Rename .slave_alloc() and .slave_destroy()

2024-12-04T20:34:28+00:00

Rename .slave_alloc() into .sdev_init() and .slave_destroy() into
.sdev_destroy(). The new names make it clear that these are actions on
SCSI devices. Make this change in the SCSI core, SCSI drivers and also
in the ATA drivers. No functionality has been changed.

This patch has been created as follows:
* Change the text "slave_alloc" into "sdev_init" in all source files
  except those in drivers/net/ and Documentation/.
* Change the text "slave_destroy" into "sdev_destroy" in all source
  files except those in drivers/net/ and Documentation/.
* Rename lpfc_no_slave() into lpfc_no_sdev().
* Manually adjust whitespace where necessary to restore vertical
  alignment (dc395x driver and include/linux/libata.h).

scsi: message: fusion: Constify struct pci_device_id

2024-11-21T02:38:24+00:00

'struct pci_device_id' is not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security.

On a x86_64, with allmodconfig, as an example:
Before:
======

  36999	   2451	     88	  39538	   9a72	drivers/message/fusion/mptfc.o

After:
=====

scsi: fusion: Remove unused variable 'rc'

2024-11-07T01:46:07+00:00

The return value of scsi_device_reprobe() is currently ignored in
_scsih_reprobe_lun(). Fixing the calling code to deal with the potential
error is non-trivial, so for now just WARN_ON().

The handling of scsi_device_reprobe()'s return value refers to
_scsih_reprobe_lun() and the following link:
