From 91d20ab9d9ca035527af503d00e1e30d6c375f2a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 9 Oct 2023 10:18:01 +0200 Subject: [PATCH] wifi: cfg80211: use system_unbound_wq for wiphy work Since wiphy work items can run pretty much arbitrary code in the stack/driver, it can take longer to run all of this, so we shouldn't be using system_wq via schedule_work(). Also, we lock the wiphy (which is the reason this exists), so use system_unbound_wq.
