All callers of ath9k_beacon_ensure_primary_slot() are preemptible / acquire a mutex except for this callchain: spin_lock_bh(&sc->sc_pcu_lock); ath_complete_reset() -> ath9k_calculate_summary_state() -> ath9k_beacon_ensure_primary_slot() It's unclear how that can be distangled, so use tasklet_disable_in_atomic() for now. This allows tasklet_disable() to become sleepable once the remaining atomic users are cleaned up.
