perf, cgroups: Fix up for new API
Ben changed the cgroup API in commit f780bdb7c1c (cgroups: add per-thread subsystem callbacks) in an incompatible way, but forgot to convert the perf cgroup bits. Avoid compile warnings and runtime splats and convert perf too ;-) Acked-by: Ben Blum <bblum@andrew.cmu.edu> Cc: Stephane Eranian <eranian@google.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1306767651.1200.2990.camel@twins Signed-off-by: Ingo Molnar <mingo@elte.hu>
