The quilt patch titled Subject: kasan: add kasan_tag_mismatch prototype has been removed from the -mm tree. Its filename was kasan-add-kasan_tag_mismatch-prototype.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: Arnd Bergmann arnd@arndb.de Subject: kasan: add kasan_tag_mismatch prototype Date: Tue, 9 May 2023 16:57:20 +0200
The kasan sw-tags implementation contains one function that is only called from assembler and has no prototype in a header. This causes a W=1 warning:
mm/kasan/sw_tags.c:171:6: warning: no previous prototype for 'kasan_tag_mismatch' [-Wmissing-prototypes] 171 | void kasan_tag_mismatch(unsigned long addr, unsigned long access_info,
Add a prototype in the local header to get a clean build.
