treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

scsi: Change the return type of the .queuecommand() callback

2026-01-24T02:32:34+00:00

In clang version 21.1 and later the -Wimplicit-enum-enum-cast warning option has been introduced. This warning is enabled by default and can be used to catch .queuecommand() implementations that return another value than 0 or one of the SCSI_MLQUEUE_* constants. Hence this patch that changes the return type of the .queuecommand() implementations from 'int' into 'enum scsi_qc_status'. No functionality has been changed.

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: 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: 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()).
