Subject: kasan: clear metadata functions for tag-based modes
Date: Mon, 5 Sep 2022 23:05:24 +0200
Remove implementations of the metadata-related functions for the tag-based modes.
The following patches in the series will provide alternative implementations.
As of this patch, the tag-based modes no longer collect alloc and free stack traces. This functionality will be restored later in the series.
