[RFC][PATCH 0/8] perf pmu interface
These patches prepare the perf code for multiple pmus (no user interface yet, Lin Ming is working on that). These patches remove all weak functions and rework the struct pmu interface. The latter is inspired by the work Frederic is doing to to filter out IRQ contexts. These patches are very prelimenary, they h... 16 Jun 2010 13:15

[RFC][PATCH 1/8] perf, x86: Fix Nehalem PMU quirk
The idea was to run all three counters, which means we need to program 7 into the enable mask, not 3 (which is two bits).

[PATCH] procfs: Do not release pid_ns->proc_mnt too early
Detached tasks are not seen by zap_pid_ns_processes()->sys_wait4(), so that release_task()->proc_flush_task() of container init can be called before it is for some detached tasks in the namespace. Pin proc_mnt's in copy_process(), so that proc_flush_task() becomes safe whatever the ordering of tasks. Signed-of... 16 Jun 2010 13:15
