The quilt patch titled Subject: mm/slab: add is_kmalloc_cache() helper function has been removed from the -mm tree. Its filename was mm-slab-add-is_kmalloc_cache-helper-function.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Feng Tang <feng.tang@xxxxxxxxx> Subject: mm/slab: add is_kmalloc_cache() helper function Date: Wed, 4 Jan 2023 14:06:04 +0800 commit 6edf2576a6cc ("mm/slub: enable debugging memory wasting of kmalloc") introduces 'SLAB_KMALLOC' bit specifying whether a kmem_cache is a kmalloc cache for slab/slub (slob doesn't have dedicated kmalloc caches). Add a helper inline function for other components like kasan to simplify code.
