From 0b3fcf178deefd7b64154c2c0760a2c63df0b74f Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Mon, 3 Jan 2011 18:20:01 +0200 Subject: perf_events: Move code around to prepare for cgroup In particular this patch move perf_event_exit_task() before cgroup_exit() to allow for cgroup support. The cgroup_exit() function detaches the cgroups attached to a task. Other movements include hoisting some definitions and inlines at the top of perf_event.c Signed-off-by: Stephane Eranian Signed-off-by: Peter Zijlstra LKML-Reference: <4d22058b.cdace30a.4657.ffff95b1@mx.google.com> Signed-off-by: Ingo Molnar --- kernel/exit.c | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) (limited to 'kernel/exit.c') diff --git a/kernel/exit.c b/kernel/exit.c index 676149a4ac5f..8cb89045ecf3 100644 --- a/kernel/exit.c +++ b/kernel/exit.c @@ -994,6 +994,15 @@ NORET_TYPE void do_exit(long code) exit_fs(tsk); check_stack_usage(); exit_thread(); + + /* + * Flush inherited counters to the parent - before the parent + * gets woken up by child-exit notifications. + * + * because of cgroup mode, must be called before cgroup_exit() + */ + perf_event_exit_task(tsk); + cgroup_exit(tsk, 1); if (group_dead) @@ -1007,11 +1016,6 @@ NORET_TYPE void do_exit(long code) * FIXME: do that only when needed, using sched_exit tracepoint */ flush_ptrace_hw_breakpoint(tsk); - /* - * Flush inherited counters to the parent - before the parent - * gets woken up by child-exit notifications. - */ - perf_event_exit_task(tsk); exit_notify(tsk, group_dead); #ifdef CONFIG_NUMA -- cgit v1.2.3
