From: Marco Crivellari Date: Tue, 5 May 2026 12:41:02 +0000 (+0200) Subject: umh: replace use of system_unbound_wq with system_dfl_wq X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7fcb7afb9b5eecb85904b16747b6eb04b0880c3b;p=thirdparty%2Fkernel%2Flinux.git umh: replace use of system_unbound_wq with system_dfl_wq This patch continues the effort to refactor workqueue APIs, which has begun with the changes introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The point of the refactoring is to eventually alter the default behavior of workqueues to become unbound by default so that their workload placement is optimized by the scheduler. Before that to happen, workqueue users must be converted to the better named new workqueues with no intended behaviour changes: system_wq -> system_percpu_wq system_unbound_wq -> system_dfl_wq This way the old obsolete workqueues (system_wq, system_unbound_wq) can be removed in the future.
