Subject: [PATCH 0/5] tracing: Cleanups with use of guard() and __free()


This is a cleanup to use guard() and __free() where possible.

Steven Rostedt (5):
      tracing: Remove unneeded goto out logic
      tracing: Add guard(ring_buffer_nest)
      tracing: Add guard() around locks and mutexes in trace.c
      tracing: Use __free(kfree) in trace.c to remove gotos
      ring-buffer: Convert ring_buffer_write() to use guard(preempt_notrace)
