It would be nice if it went to stable, but I'd defer to the Kasan maintainers. The kasan_arch_is_ready() checks went in a while back, but there wasn't a meaningful user until the powerpc support went in, so I'd target that: Fixes: 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN support") Cc: sta...@vger.kernel.org # v5.19+ cheers
