2026-02-21	Convert 'alloc_obj' family to use the new default GFP_KERNEL argument	Linus Torvalds
	This was done entirely with mindless brute force, using git grep -l '\<k[vmz]alloc_objs(., GFP_KERNEL)' \| xargs sed -i 's/\(alloc_objs(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21	treewide: Replace kmalloc with kmalloc_obj for non-scalar types	Kees Cook
	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 <kees@kernel.org>
2022-02-22	scsi: Remove drivers/scsi/scsi.h	Bart Van Assche
	The following two header files have the same file name: include/scsi/scsi.h and drivers/scsi/scsi.h. This is confusing. Remove the latter since the following note was added in drivers/scsi/scsi.h in 2004: "NOTE: this file only contains compatibility glue for old drivers. All these wrappers will be removed sooner or later. For new code please use the interfaces declared in the headers in include/scsi/" Link: https://lore.kernel.org/r/20220218195117.25689-7-bvanassche@acm.org Cc: Christoph Hellwig <hch@lst.de> Cc: Ming Lei <ming.lei@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.

2021-09-22	scsi: acornscsi: Remove tagged queuing vestiges	Hannes Reinecke
	The acornscsi driver has a config option to enable tagged queuing, but this option gets disabled in the driver itself with the comment 'needs to be debugged'. As this is a _really_ old driver I doubt anyone will be wanting to invest time here, so remove the tagged queue vestiges and make our lives easier.

2018-06-12	treewide: kmalloc() -> kmalloc_array()	Kees Cook
	The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) \| kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
