[RFC PATCH 0/4] workqueue: Introduce low-level unbound wq sysfs cpumask

[Frederic Weisbecker]

Hi,

So this new version takes another direction suggested by Tejun.
Now we have a cpumask at the root of the workqueue directory
to bound the affinity of all unbound workqueues.

It's an early release as more plumbing is required. Most notably:

* Drop last patch and integrate Lai's instead to support
apply_workqueue_attrs() on ordered workqueues: https://lkml.org/lkml/2014/4/15/181

* Handle cpumask value expansion (in fact the per wq cpumask must be
stored seperately than the effective cpumask to handle that correctly).
I should take care of that in the next version.

But I prefer to post the current state now in case I'm wandering off.

Thanks,
