Subject: [PATCH 16/32] kasan: only define metadata offsets for Generic mode
Date:   Mon, 13 Jun 2022 22:14:07 +0200

From: Andrey Konovalov <andreyknvl@google.com>

Hide the definitions of alloc_meta_offset and free_meta_offset under
an ifdef CONFIG_KASAN_GENERIC check, as these fields are now only used
when the Generic mode is enabled.
