+Subject: [PATCH] mac80211: disable BHs/preemption in
+ ieee80211_tx_control_port()
+
+On pre-emption enabled kernels the following print was being seen due to
+missing local_bh_disable/local_bh_enable calls. mac80211 assumes that
+pre-emption is disabled in the data path.
+
+ BUG: using smp_processor_id() in preemptible [00000000] code: iwd/517
+ caller is __ieee80211_subif_start_xmit+0x144/0x210 [mac80211]
+ [...]
+ Call Trace:
+ dump_stack+0x5c/0x80
+ check_preemption_disabled.cold.0+0x46/0x51
+ __ieee80211_subif_start_xmit+0x144/0x210 [mac80211]
+
