[PATCH 2/5] perf: Support disable() after stop() on software events
If we call perf_event_stop() on a software event and then the disable() pmu callback on them after that, we'll call twice hlist_del_rcu() on the same hlist node and then bring a crash by dereferencing LIST_POISON2. Just use hlist_del_init_rcu() instead to fix this problem. This preparates for new context exclu... 10 Jun 2010 00:12

[PATCH 1/5] perf: Provide a proper stop action for software events
In order to introduce new context exclusions, software events will have to eventually stop when needed. We'll want perf_event_stop() to act on every events. To achieve this, remove the stub stop/start pmu callbacks of software and tracepoint events. This may even optimize the case of hardware and software even... 10 Jun 2010 00:12
