In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: use work to update rate to avoid RCU warning The ieee80211_ops::sta_rc_update must be atomic, because ieee80211_chan_bw_change() holds rcu_read lock while calling drv_sta_rc_update(), so create a work to do original things. Voluntary context switch within RCU read-side critical section!
