Subject: alsa-workqueue-fixes
From: Andrew Morton <akpm@xxxxxxxx>
Fix the soc code after dhowells workqueue changes.
I converted the workqueues to per-device while I was there. It seems strange
to create a new kernel thread (on each CPU!) and to then only have a single
global work to ever be queued upon it.
Plus without this, I'd have to use the _NAR stuff, gawd help me.
Does that workqueue really need to be per-cpu?
Does that workqueue really need to exist? Why not use keventd?
