From b6f4bd64f453183954184ffbc2b89d73ed8fb135 Mon Sep 17 00:00:00 2001 From: Marco Crivellari Date: Thu, 6 Nov 2025 15:29:14 +0100 Subject: [PATCH] regulator: irq_helper: replace use of system_wq with system_dfl_wq Currently if a user enqueues 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 consistency cannot be addressed without refactoring the API. This continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This specific workload do not benefit from a per-cpu workqueue, so use the default unbound workqueue (system_dfl_wq) instead.
