I send SIGSTOP to

  [PATCH 4/6] usbip: fix stub_dev usbip_sockfd_store() races leading to gpf
  [PATCH 5/6] usbip: fix vhci_hcd attach_store() races leading to gpf
  [PATCH 6/6] usbip: fix vudc usbip_sockfd_store races leading to gpf

because these patches merely converted NULL pointer dererefence bug to use-after-free bug
by breaking kthread_get_run() into kthread_create()/get_task_struct()/wake_up_process().
