Its filename was kasan-update-outdated-comment.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Kexin Sun Subject: kasan: update outdated comment Date: Thu, 12 Mar 2026 13:38:12 +0800 kmalloc_large() was renamed kmalloc_large_noprof() by commit 7bd230a26648 ("mm/slab: enable slab allocation tagging for kmalloc and friends"), and subsequently renamed __kmalloc_large_noprof() by commit a0a44d9175b3 ("mm, slab: don't wrap internal functions with alloc_hooks()"), making it an internal implementation detail. Large kmalloc allocations are now performed through the public kmalloc() interface directly, making the reference to KMALLOC_MAX_SIZE also stale (KMALLOC_MAX_CACHE_SIZE would be more accurate). Remove the references to kmalloc_large() and KMALLOC_MAX_SIZE, and rephrase the description for large kmalloc allocations.
