From 8a58fc1ce487a77dc9c87e12682b5297e4a030fa Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 20 Sep 2023 21:25:15 +0300 Subject: wifi: mac80211: relax RCU check in for_each_vif_active_link() To iterate the vif links we don't necessarily need to be in an RCU critical section, it's also possible to hold the sdata/wdev mutex. Annotate for_each_vif_active_link() accordingly.
