From: Andrey Konovalov <andreyknvl@xxxxxxxxxx> Subject: kasan: rename print_shadow_for_address to print_memory_metadata This is a preparatory commit for the upcoming addition of a new hardware tag-based (MTE-based) KASAN mode. Hardware tag-based KASAN won't be using shadow memory, but will reuse this function. Rename "shadow" to implementation-neutral "metadata". No functional changes.
