Subject: [PATCH] libata: forbid port runtime pm by default
|
||||
|
||||
Forbid port runtime pm by default because it has known hotplug issue.
|
||||
User can allow it by, for example
|
||||
|
||||
echo auto > /sys/devices/pci0000:00/0000:00:1f.2/ata2/power/control

Is possible that we will arm the tid_rx->reorder_timer after
|
||||
del_timer_sync() in ___ieee80211_stop_rx_ba_session(). We need to stop
|
||||
timer after RCU grace period finish, so move it to
|
||||
ieee80211_free_tid_rx(). Timer will not be armed again, as
|
||||
rcu_dereference(sta->ampdu_mlme.tid_rx[tid]) will return NULL.
|
||||
|
||||
Debug object detected problem with the following warning:
|

ODEBUG: free active (active state 0) object type: timer_list hint: sta_rx_agg_reorder_timer_expired+0x0/0xf0 [mac80211]
