From 9393a3a4207f35a2cd1ff5994ed17e8fbd9ce787 Mon Sep 17 00:00:00 2001 From: Marco Crivellari Date: Wed, 5 Nov 2025 17:27:36 +0100 Subject: [PATCH] thunderbolt: Replace use of system_wq with system_percpu_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 patch 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") Replace system_wq with system_percpu_wq, keeping the old behavior. The old wq (system_wq) will be kept for a few release cycles.
