[ 23/60] tracing: Make TRACE_ITER_STOP_ON_FREE stop the correct buffer

[Greg Kroah-Hartman]

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

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

From: Alexander Z Lam <azl@xxxxxxxxxx>

commit 711e124379e0f889e40e2f01d7f5d61936d3cd23 upstream.

Releasing the free_buffer file in an instance causes the global buffer
to be stopped when TRACE_ITER_STOP_ON_FREE is enabled. Operate on the
correct buffer.
