Pull SCSI updates from James Bottomley: "Usual driver updates (qla2xxx, mpi3mr, mpt3sas, ufs) plus assorted cleanups and fixes.

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).

scsi: target: core: Add emulation for REPORT IDENTIFYING INFORMATION

2025-12-17T02:07:22+00:00

Add emulation for REPORT IDENTIFYING INFORMATION command using the configfs file 'pd_text_id_info' in target core module. The configfs file is created in /sys/kernel/config/target/core// /wwn/. An emulation function, spc_emulate_report_id_info(), is defined to return the identification string based on the contents of 'pd_text_id_info'. The details of the REPORT IDENTIFYING INFORMATION command is defined in section 6.32 of SPC4.

scsi: target: core: Constify struct target_opcode_descriptor

2025-05-21T02:11:03+00:00

Instances of 'struct target_opcode_descriptor' are not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security, especially when the structure holds some function pointers.

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.
