From: Marco Crivellari Date: Wed, 5 Nov 2025 15:16:49 +0000 (+0100) Subject: PCI: endpoint: Replace use of system_wq with system_percpu_wq X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0d325cbdc5ce97e6bd391d6a742607814025e69d;p=thirdparty%2Fkernel%2Flinux.git PCI: endpoint: Replace use of system_wq with system_percpu_wq Currently work items enqueued by schedule_delayed_work() use "system_wq" (a per-CPU wq) while queue_delayed_work() uses 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 workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue() flag in: 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") Replace system_wq with system_percpu_wq, keeping the same behavior. The old wq (system_wq) will be kept for a few release cycles.
