JIRA: https://issues.redhat.com/browse/RHEL-94929 Upstream Status: merged into the linux.git commit 930c2ea566aff59e962c50b2421d5fcc3b98b8be Author: Marco Crivellari <marco.crivellari@suse.com> Date: Sat Jun 14 15:35:30 2025 +0200 workqueue: Add new WQ_PERCPU flag 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. This patch adds a new WQ_PERCPU flag to explicitly request the use of the per-CPU behavior. Both flags coexist for one release cycle to allow callers to transition their calls. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default. tj: Merged doc patch.
