Inspired by hostap shutdown potentially taking a long time (which is in part also its fault), I took a closer look at the station removal code and I think it's too complex. Only a single driver (iwlmvm) has a need for an RCU grace period after sta_state() returns, and that can easily be addressed differently. So consolidate many of the synchronize_rcu()/_net() in these paths and get rid of the rcu_barrier() stuff completely. Testing is still pending, but it should improve timing. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
