[PATCH 16/32] kasan: only define metadata offsets for Generic mode

From: andrey . konovalov
Date: Mon Jun 13 2022 - 16:55:57 EST


From: Andrey Konovalov <andreyknvl@xxxxxxxxxx>

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.
