Subject: [PATCH tip/core/rcu 1/3] tracing: Export trace_clock_local()
Date: Sat,  5 Jan 2013 09:04:17 -0800	[thread overview]
Message-ID: <1357405459-13675-1-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20130105170356.GA13534@linux.vnet.ibm.com>

From: "Paul E. McKenney" <paul.mckenney@linaro.org>

The rcutorture tests need to be able to trace the time of the
beginning of an RCU read-side critical section, and thus need access
to trace_clock_local().  This commit therefore adds a the needed
EXPORT_SYMBOL_GPL().
