Subject: [PATCH] framewarn: expand KASAN_EXTRA exception to KASAN
Date:   Fri, 21 Sep 2018 02:15:13 +0200
Message-Id: <20180921001513.12504-1-Jason@zx2c4.com>

Precedence: bulk

It turns out that KASAN in general will bloat stack frames in unexpected
ways, not just KASAN_EXTRA. So, this patch trivially changes that
default to be associated with KASAN instead of KASAN_EXTRA.
