Subject: [ 17/74] tracing: Do not call kmem_cache_free() on allocation failure

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Namhyung Kim <namhyung.kim@....com>

commit aaf6ac0f0871cb7fc0f28f3a00edf329bc7adc29 upstream.

There's no point calling it when _alloc() failed.
