Subject: [PATCH v3 0/2] rust: add new workqueue functions

Hi,

Recently the workqueue code has been changed introducing two new workqueue,
system_percpu_wq and system_dfl_wq, as a future replacement for system_wq and
system_unbound_wq respectively.

The change has been introduced by:
    'commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")'

The old workqueue(s) will be removed in a next release cycle.

=== Introduced Changes by this series ===

1) [P 1-2] Add wrapper for the new workqueues
  -   This change introduce two new Rust functions in order to add a wrapper for
      the new wq(s) defined in the C code.


Thanks!

---
Changes in v3:
- added a proper comment documenting the new added functions.

Changes in v2:
- added system_percpu() and system_dfl() in order to use the new
  wq defined in the C code.

- fixed misleading paragraph in the commit log (no warnings are currently
  present).

Marco Crivellari (2):
  rust: replace use of system_unbound_wq with system_dfl_wq
  rust: replace use of system_wq with system_percpu_wq
