Merge patch series "Add WQ_PERCPU to alloc_workqueue() users"

Browse source 
Marco Crivellari <marco.crivellari@suse.com> says:

Hi,

This series continues the effort to refactor the Workqueue API.
No behavior changes are introduced by this series.

=== Recent changes to the WQ API ===

The following, address the recent changes in the Workqueue API:

- commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
- commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

The old workqueues will be removed in a future release cycle and
unbound will become the implicit default.

=== Introduced Changes by this series ===

1) [P 1-2-3] add WQ_PERCPU to  alloc_workqueue() users

    With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
    any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
    must now use WQ_PERCPU.

    WQ_UNBOUND will be removed in future.
