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.

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).
