[37/98] perf: Fix resource leak in failure path of perf_event_open()

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Tejun Heo <tj@xxxxxxxxxx>

commit 048c852051d2bd5da54a4488bc1f16b0fc74c695 upstream.

perf_event_open() kfrees event after init failure which doesn't
release all resources allocated by perf_event_alloc().  Use
free_event() instead.
