Subject: [PATCH v3 0/2] Replace system_unbound_wq with system_dfl_wq
Date: Thu,  2 Apr 2026 15:41:45 +0200	[thread overview]
Message-ID: <20260402134147.285401-1-marco.crivellari@suse.com> (raw)

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 following, address the aforementioned changes in the Workqueue API:

- commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
- commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")

The old workqueues will be removed in a future release cycle.

=== Introduced Changes by this series ===

1) [P 1-2]  Replace uses of system_wq and system_unbound_wq

    system_unbound_wq is to be used when locality is not required.
    Nothing in its name make clear this should be used when locality is not
    required, so system_unbound_wq has been replaced with system_dfl_wq.

Thanks!
