The patch titled Subject: mm: move kmem_cache_init() declaration to mm/slab.h has been added to the -mm mm-unstable branch. Its filename is mm-move-kmem_cache_init-declaration-to-mm-slabh.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-move-kmem_cache_init-declaration-to-mm-slabh.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: "Mike Rapoport (IBM)" <rppt@xxxxxxxxxx> Subject: mm: move kmem_cache_init() declaration to mm/slab.h Date: Mon, 20 Mar 2023 00:00:06 +0200 kmem_cache_init() is called only from mm_core_init(), there is no need to declare it in include/linux/slab.h Move kmem_cache_init() declaration to mm/slab.h Link: https://lkml.kernel.org/r/20230319220008.2138576-14-rppt@xxxxxxxxxx Signed-off-by: Mike Rapoport (IBM) <rppt@xxxxxxxxxx> Reviewed-by: David Hildenbrand <david@xxxxxxxxxx> Cc: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx> Cc: Mel Gorman <mgorman@xxxxxxx> Cc: Michal Hocko <mhocko@xxxxxxxxxx> Cc: Thomas Bogendoerfer <tsbogend@xxxxxxxxxxxxxxxx> Cc: Vlastimil Babka <vbabka@xxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- --- a/include/linux/slab.h~mm-move-kmem_cache_init-declaration-to-mm-slabh +++ a/include/linux/slab.h @@ -167,7 +167,6 @@ struct mem_cgroup; /* * struct kmem_cache related prototypes */ -void __init kmem_cache_init(void); bool slab_is_available(void); struct kmem_cache *kmem_cache_create(const char *name, unsigned int size, --- a/mm/mm_init.c~mm-move-kmem_cache_init-declaration-to-mm-slabh +++ a/mm/mm_init.c @@ -27,6 +27,7 @@ #include <linux/swap.h> #include <linux/cma.h> #include "internal.h" +#include "slab.h" #include "shuffle.h" #include <asm/setup.h> --- a/mm/slab.h~mm-move-kmem_cache_init-declaration-to-mm-slabh +++ a/mm/slab.h @@ -4,6 +4,7 @@ /* * Internal slab definitions */ +void __init kmem_cache_init(void); /* Reuses the bits in struct page */ struct slab { _ Patches currently in -mm which might be from rppt@xxxxxxxxxx are mm-move-get_page_from_free_area-to-mm-page_allocc.patch mips-fix-comment-about-pgtable_init.patch mm-cma-move-init_cma_reserved_pages-to-cmac-and-make-it-static.patch mm-page_alloc-add-helper-for-checking-if-check_pages_enabled.patch mm-move-most-of-core-mm-initialization-to-mm-mm_initc.patch mm-handle-hashdist-initialization-in-mm-mm_initc.patch mm-page_alloc-rename-page_alloc_init-to-page_alloc_init_cpuhp.patch init-fold-build_all_zonelists-and-page_alloc_init_cpuhp-to-mm_init.patch initmm-move-mm_init-to-mm-mm_initc-and-rename-it-to-mm_core_init.patch mm-move-pgtable_init-to-mm-mm_initc-and-make-it-static.patch mm-move-init_mem_debugging_and_hardening-to-mm-mm_initc.patch initmm-fold-late-call-to-page_ext_init-to-page_alloc_init_late.patch mm-move-mem_init_print_info-to-mm_initc.patch mm-move-kmem_cache_init-declaration-to-mm-slabh.patch mm-move-vmalloc_init-declaration-to-mm-internalh.patch maintainers-extend-memblock-entry-to-include-mm-initialization.patch
