scsi: usb: Rename the RESERVE and RELEASE constants

2025-05-29T09:13:25+00:00

[ Upstream commit 0ea163a18b17f9e0f8350bb348ae69c4a376be66 ]

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:
======
   text	   data	    bss	    dec	    hex	filename
  36999	   2451	     88	  39538	   9a72	drivers/message/fusion/mptfc.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  37415	   2043	     88	  39546	   9a7a	drivers/message/fusion/mptfc.o

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:

scsi: mptfusion: Remove #ifndef GENKSYMS / #endif

2024-10-04T02:00:08+00:00

Except for preventing build errors, there shouldn't be any conditionals in
kernel drivers on __GENKSYMS__. Hence remove an #ifndef __GENKSYMS__ / #endif
pair from the MPT Fusion driver.

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43+00:00

no_llseek had been defined to NULL two years ago, in commit 868941b14441
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

scsi: fusion: mptctl: Use min() macro

2024-09-13T00:23:03+00:00

Using the real macro is usually more intuitive and readable when the
original file is guaranteed to contain the minmax.h header file and compile
correctly.
