treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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

2026-01-24T02:32:34Z

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: Add PM_EVENT_POWEROFF into suspend callbacks

2025-11-14T16:05:53Z

If the PM core uses hibernation callbacks for powering off the system, drivers will receive PM_EVENT_POWEROFF and should handle it the same as they previously handled PM_EVENT_HIBERNATE. Support this case in the scsi driver. No functional changes. Reviewed-by: Martin K.

scsi: stex: Fix reboot_notifier leak in probe error path

2025-11-08T17:11:06Z

In stex_probe(), register_reboot_notifier() is called at the beginning, but if any subsequent initialization step fails, the function returns without unregistering the notifier, resulting in a resource leak. Add unregister_reboot_notifier() in the out_disable error path to ensure proper cleanup on all failure paths.

scsi: Convert SCSI drivers to .sdev_configure()

2024-12-04T20:34:28Z

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.
