There are multiple other instances which could use similar str_on_off() as well.

mm/kasan/hw_tags.c:             kasan_vmalloc_enabled() ? "on" : "off",
mm/kasan/hw_tags.c:             kasan_stack_collection_enabled() ? "on" : "off");
mm/kasan/sw_tags.c:             kasan_stack_collection_enabled() ? "on" : "off");
mm/mm_init.c:           stack, want_init_on_alloc(GFP_KERNEL) ? "on" : "off",
mm/mm_init.c:           want_init_on_free() ? "on" : "off");

I would suggest converting all of them together in a single patch instead.
