From: Marco Crivellari Date: Tue, 5 May 2026 12:41:01 +0000 (+0200) Subject: rapidio: rio: add WQ_PERCPU to alloc_workqueue users X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=bdefddd9d1b371db1fa4de82be290dfb922b825d;p=thirdparty%2Fkernel%2Flinux.git rapidio: rio: 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.
