Parvi Kaustubhi 5bb3c1e9d4 IB/usnic: Fix deadlock ... There is a dead lock in usnic ib_register and netdev_notify path. usnic_ib_discover_pf() | mutex_lock(&usnic_ib_ibdev_list_lock); | usnic_ib_device_add(); | ib_register_device() | usnic_ib_query_port() | mutex_lock(&us_ibdev->usdev_lock); | ib_get_eth_speed() | rtnl_lock() order of lock: &usnic_ib_ibdev_list_lock -> usdev_lock -> rtnl_lock rtnl_lock() | usnic_ib_netdevice_event() | mutex_lock(&usnic_ib_ibdev_list_lock); order of lock: rtnl_lock -> &usnic_ib_ibdev_list_lock Solution is to use the core's lock-free ib_device_get_by_netdev() scheme to lookup ib_dev while handling netdev & inet events.
