6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@xxxxxxxxx>
[ Upstream commit 5ea82df1f50e42416d0a8a7c42d37cc1df1545fe ]
In mesh_fast_tx_flush_addr() we already hold the lock, so
don't need additional hashtable RCU protection. Use the
rhashtable_lookup_fast() variant to avoid RCU protection
warnings.
Fixes: d5edb9ae8d56 ("wifi: mac80211: mesh fast xmit support")
