From: Marco Crivellari Date: Fri, 14 Nov 2025 14:16:17 +0000 (+0100) Subject: driver core: replace use of system_unbound_wq with system_dfl_wq X-Git-Tag: v6.19-rc1~90^2~6 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e40ad215cea21464d516790f263dc3df69174efe;p=thirdparty%2Fkernel%2Fstable.git driver core: replace use of system_unbound_wq with system_dfl_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. 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_dfl_wq because system_unbound_wq is going away as part of a workqueue restructuring.
