Hi Daniel,

No worries, thanks for your reply and the Ack!

BTW, the introduction of WQ_PERCPU here it's only to keep the same old
behavior, but make explicit it is per-cpu and not unbound.

Looking at the code there is a big chance this can already be
converted to unbound anyhow,
(WQ_UNBOUND, explicitly) because I don't see per-cpu variables around.
Otherwise this can
be done in a later step, and keep the per-cpu behavior for now, like
it has been till now.

Thanks!
