	Now that we have atomic.h, we should convert all of the existing refcounts to use it.

2011-02-16	perf tool: Add cgroup support	Stephane Eranian	1	-0/+17
	This patch adds the ability to filter monitoring based on container groups (cgroups) for both perf stat and perf record. It is possible to monitor multiple cgroup in parallel. There is one cgroup per event. The cgroups to monitor are passed via a new -G option followed by a comma separated list of cgroup names. The cgroup filesystem has to be mounted. Given a cgroup name, the perf tool finds the corresponding directory in the cgroup filesystem and opens it. It then passes that file descriptor to the kernel. Example: $ perf stat -B -a -e cycles:u,cycles:u,cycles:u -G test1,,test2 -- sleep 1 Performance counter stats for 'sleep 1': 2,368,667,414 cycles test1 2,369,661,459 cycles <not counted> cycles test2 1.001856890 seconds time elapsed Signed-off-by: Stephane Eranian <eranian@google.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <4d590290.825bdf0a.7d0a.4890@mx.google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
