From ee518f914cd901c16fa08a6f228b266551f72a6a Mon Sep 17 00:00:00 2001 From: Marco Crivellari Date: Mon, 22 Sep 2025 11:32:43 +0200 Subject: [PATCH] wifi: mt76: replace use of system_wq with system_percpu_wq Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. For more details see the Link tag below. This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") Switch to using system_percpu_wq because system_wq is going away as part of a workqueue restructuring.
