Subject: [PATCH 3/3] tracing: Add rcu annotation for event_trigger_data.filter
Date: Sat, 21 Dec 2013 16:44:02 -0600	[thread overview]
Message-ID: <676c1cf2faa6715acefcbc5de5d75acd71586496.1387662969.git.tom.zanussi@linux.intel.com> (raw)
In-Reply-To: <cover.1387662969.git.tom.zanussi@linux.intel.com>
In-Reply-To: <cover.1387662969.git.tom.zanussi@linux.intel.com>

sparse complains about rcu_assign_pointer() and RCU_INIT_POINTER()
assignments to event_trigger_data filter; annotate it with __rcu to
get rid of the warning.
