From c71420db653aba30a234d1e4cf86dde376e604fa Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 15 Jun 2022 09:20:45 +0200 Subject: wifi: mac80211: RCU-ify link STA pointers We need to be able to access these in a race-free way under traffic while adding/removing them, so RCU-ify the pointers. This requires passing a link_sta to a lot of functions so we don't have to do the RCU handling everywhere.
