From 9870d350e45a5724ee25f77aa0b6d053c9b766db Mon Sep 17 00:00:00 2001 From: Marco Crivellari Date: Thu, 18 Sep 2025 16:24:25 +0200 Subject: net: 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. system_unbound_wq should be the default workqueue so as not to enforce locality constraints for random work whenever it's not required. Adding system_dfl_wq to encourage its use when unbound work should be used. The old system_unbound_wq will be kept for a few release cycles.
