From: Marco Crivellari Date: Thu, 30 Oct 2025 15:47:36 +0000 (+0100) Subject: ACPI: OSL: replace use of system_wq with system_percpu_wq X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6447ece47c7399894f36bbfda3dfce13d0330c76;p=thirdparty%2Fkernel%2Flinux.git ACPI: OSL: 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 consistency cannot be addressed without refactoring the API. system_wq should be the per-cpu workqueue, yet in this name nothing makes that clear, so replace system_wq with system_percpu_wq. The old wq (system_wq) will be kept for a few release cycles.
