tracing: remove recursive test from ring_buffer_event_discard
The ring_buffer_event_discard is not tied to ring_buffer_lock_reserve. It can be called inside or outside the reserve/commit. Even if it is called inside the reserve/commit the commit part must also be called. Only ring_buffer_discard_commit can be used as a replacement for ring_buffer_unlock_commit. This patch removes the trace_recursive_unlock from ring_buffer_event_discard since it would be the wrong place to do so. [Impact: prevent breakage in trace recursive testing ] Cc: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
