Message-Id: <1505950075-50223-16-git-send-email-keescook@chromium.org>
Date: Wed, 20 Sep 2017 16:27:39 -0700
From: Kees Cook <keescook@...omium.org>
To: Thomas Gleixner <tglx@...utronix.de>
Cc: Kees Cook <keescook@...omium.org>, linux-kernel@...r.kernel.org
Subject: [PATCH v2 15/31] timer: Additional init_timer() -> setup_timer() conversions
This converts several more cases of open-coded setup_timer() calls that
the setup_timer.cocci script was not able to handle itself.
Signed-off-by: Kees Cook <keescook@...omium.org>
