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... Reviewed-by: Martin K. Petersen Reviewed-by: Christoph Hellwig Acked-by: Jens Axboe Signed-off-by: Al Viro

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: ips: Do not try to abort command from host reset

2023-10-13T18:23:15+00:00

The code for aborting an outstanding command is a copy of the functionality from command abort. As we already have called this function once we reach host reset there's no point in trying to do so again.

scsi: ips: Replace kmap_atomic() with kmap_local_page()

2023-01-18T23:41:12+00:00

kmap_atomic() is deprecated in favor of kmap_local_page(). Therefore, replace kmap_atomic() with kmap_local_page() in ips_is_passthru(). In the meantime remove an unnecessary comment, align code, and remove spaces. kmap_atomic() is implemented like a kmap_local_page() which also disables page-faults and preemption (the latter only for !PREEMPT_RT kernels). The code within the mapping/unmapping in ips_is_passthru() is already in atomic context because of a call to local_irq_save() and kmap_local_page() can be called in atomic context too (including interrupts). Therefore, a mere replacement of the old API with the new one is all it is required (i.e., there is no need to explicitly add any calls to pagefault_disable() and/or preempt_disable()).

scsi: Remove drivers/scsi/scsi.h

2022-02-23T02:11:02+00:00

The following two header files have the same file name: include/scsi/scsi.h and drivers/scsi/scsi.h. This is confusing. Remove the latter since the following note was added in drivers/scsi/scsi.h in 2004: "NOTE: this file only contains compatibility glue for old drivers. All these wrappers will be removed sooner or later. For new code please use the interfaces declared in the headers in include/scsi/" Link: https://lore.kernel.org/r/20220218195117.25689-7-bvanassche@acm.org Cc: Christoph Hellwig Cc: Ming Lei Reviewed-by: Hannes Reinecke Reviewed-by: Himanshu Madhani Reviewed-by: Johannes Thumshirn Acked-by: Greg Kroah-Hartman Signed-off-by: Bart Van Assche Signed-off-by: Martin K.

scsi: core: Remove the 'done' argument from SCSI queuecommand_lck functions

2021-10-17T01:32:16+00:00

The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and also that of the scsi_done function to the queuecommand_lck() function implementations. Remove the 'scsi_done' argument since its address is now a constant and instead call 'scsi_done' directly from inside the queuecommand_lck() functions.
