From 8bf705d130396e69c04cd8e6e010244ad2ce71f4 Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Mon, 29 Jan 2018 18:26:05 +0100 Subject: locking/atomic/x86: Switch atomic.h to use atomic-instrumented.h Add arch_ prefix to all atomic operations and include . This will allow to add KASAN instrumentation to all atomic ops.
