Subject: [PATCH -tip v2 10/11] compiler.h: Move function attributes to compiler_types.h
From:   Marco Elver <elver@google.com>
To:     elver@google.com

Content-Type: text/plain; charset="UTF-8"
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Cleanup and move the KASAN and KCSAN related function attributes to
compiler_types.h, where the rest of the same kind live.

No functional change intended.
