From: Marco Crivellari Date: Thu, 27 Nov 2025 14:41:23 +0000 (+0100) Subject: platform/surface: acpi-notify: add WQ_PERCPU to alloc_workqueue users X-Git-Tag: v6.19-rc1~42^2~10 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f03dd5dd736d6aea94406a273be2a10f84bc60e1;p=thirdparty%2Fkernel%2Flinux.git platform/surface: acpi-notify: add WQ_PERCPU to alloc_workqueue users This continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") The refactoring is going to alter the default behavior of alloc_workqueue() to be unbound by default. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. For more details see the Link tag below. In order to keep alloc_workqueue() behavior identical, explicitly request WQ_PERCPU.
