Subject: [PATCH mm v3 16/34] kasan: only define metadata offsets for Generic mode
Date:   Mon,  5 Sep 2022 23:05:31 +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.
