To isolate CPUs (isolate from hrtimers) from sysfs using cpusets, we need some
support from the hrtimer core. i.e. A routine hrtimer_quiesce_cpu() which would
migrate away all the unpinned hrtimers, but shouldn't touch the pinned ones.
This patch creates this routine.

'Pinned' information would be required in migrate_hrtimers() now, as we can
migrate non-pinned timers away without a hotplug (i.e. with cpuset.quiesce). And
so we may need to identify pinned timers now, as we can't migrate them.
This patch reuses the timer->state variable for setting this flag as there were
enough number of free bits available in this variable. And there is no point
increasing size of this struct by adding another field.

This reverts commit c5616f2f874faa20b59b116177b99bf3948586df.
If we re-init the per-cpu boostgroup spinlock every time that
we add a new boosted cgroup, we can easily wipe out (reinit)
a spinlock struct while in a critical section. We should only
be setting up the per-cpu boostgroup data, and the spin_lock
initialization need only happen once - which we're already
doing in a postcore_initcall.
For example:
-------- CPU 0 -------- | -------- CPU1 --------
cgroupX boost group added |
schedtune_enqueue_task |
acquires(bg->lock) | cgroupY boost group added
| for_each_cpu()
| raw_spin_lock_init(bg->lock)
releases(bg->lock) |
BUG (already unlocked) |
|
This results in the following BUG from the debug spinlock code:
BUG: spinlock already unlocked on CPU#5, rcuop/6/68
