Subject: [PATCH 09/35] kasan: don't duplicate config dependencies
Date: Fri, 14 Aug 2020 19:26:51 +0200 [thread overview]
Message-ID: <0197bbc0050e20ffdbf43eb8300af245c5c169db.1597425745.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1597425745.git.andreyknvl@google.com>
Both KASAN_GENERIC and KASAN_SW_TAGS have common dependencies, move
those to KASAN.
