Subject: Re: [PATCH V4 2/4] PHYLIB: queue work on unbound wq
From: Viresh Kumar <viresh.kumar@...aro.org>

> Phylib uses workqueues for multiple purposes. There is no real dependency of
> scheduling these on the cpu which scheduled them.
>
> On a idle system, it is observed that and idle cpu wakes up many times just to

> This patch replaces system_wq with system_unbound_wq for PHYLIB.
