Subject: [PATCH v9 12/44] kasan: don't duplicate config dependencies
Date: Tue, 10 Nov 2020 23:10:09 +0100	[thread overview]
Message-ID: <fc3f94183e4229363d0a891abc791af5b85d20f7.1605046192.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1605046192.git.andreyknvl@google.com>

Both KASAN_GENERIC and KASAN_SW_TAGS have common dependencies, move
those to KASAN.
