Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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

PCI: Use PCI_HEADER_TYPE_* instead of literals

2023-10-03T16:55:59+00:00

Replace literals under drivers/pci/ with PCI_HEADER_TYPE_MASK, PCI_HEADER_TYPE_NORMAL, and PCI_HEADER_TYPE_MFD. Also replace !! boolean conversions with FIELD_GET().

Add SPDX GPL-2.0+ to all PCI files that specified the GPL and allowed either GPL version 2 or any later version. Remove the boilerplate GPL version 2 or later language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

PCI: Remove unnecessary messages for memory allocation failures

2018-01-17T14:41:41+00:00

Per ebfdc40969f2 ("checkpatch: attempt to find unnecessary 'out of memory' messages"), when a memory allocation fails, the memory subsystem emits generic "out of memory" messages (see slab_out_of_memory() for some of this logging). Therefore, additional error messages in the caller don't add much value. Remove messages that merely report "out of memory". This preserves some messages that report additional information, e.g., allocation failures that mean we drop hotplug events. This issue was detected by using the Coccinelle software.
