Subject: [PATCH 06/10] nohz: Define meaningful symbol for nohz full timekeeper
Date: Sat, 19 Jul 2014 02:44:17 +0200 [thread overview]
Message-ID: <1405730661-9355-7-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1405730661-9355-1-git-send-email-fweisbec@gmail.com>
The nohz full timekeeper is always CPU 0. Lets add it to the list of
special tick_do_timer_cpu symbols for more self explanatory code.
