Subject: [PATCH 4/5] ftrace: rebuild everything on change to FTRACE_MCOUNT_RECORD
Content-Disposition: inline; filename=ftrace-compile-all-for-mcount-change.patch
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

When enabling or disabling CONFIG_FTRACE_MCOUNT_RECORD, we want a full
kernel compile to handle the adding of the __mcount_loc sections.
