Subject: [PATCH 1/4] kasan: prevent tracing of tags.c
Date: Wed, 20 Feb 2019 13:45:26 +0100 [thread overview]
Message-ID: <9c4c3ce5ccfb894c7fe66d91de7c1da2787b4da4.1550602886.git.andreyknvl@google.com> (raw)
Similarly to 0d0c8de8 ("kasan: mark file common so ftrace doesn't trace
it") add the -pg flag to mm/kasan/tags.c to prevent conflicts with
tracing.
