Subject: [PATCH 2/3] uptime_proc_show: use get_monotonic_boottime()
Date: Mon, 10 Jun 2013 20:33:20 +0200 [thread overview]
Message-ID: <20130610183320.GA14405@redhat.com> (raw)
In-Reply-To: <20130610183300.GA14379@redhat.com>
Change uptime_proc_show() to use get_monotonic_boottime() instead
of do_posix_clock_monotonic_gettime() + monotonic_to_bootbased().
