From: Marco Crivellari Date: Fri, 5 Sep 2025 09:10:15 +0000 (+0200) Subject: ASoC: replace use of system_unbound_wq with system_dfl_wq X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9e5eb8b49ffe3c173bf7b8c338a57dfa09fb4634;p=users%2Fhch%2Fmisc.git ASoC: 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. queue_work() / queue_delayed_work() / mod_delayed_work() will now use the new unbound wq: whether the user still use the old wq a warn will be printed along with a wq redirect to the new one. The old system_unbound_wq will be kept for a few release cycles.
