Since I haven't received it, here comes an update.

Changes since v1:

  Tetsuo Handa found that the PTR_ERR() access in usbip_prepare_threads()
  in v1 was wrong, and fixed it in v2.

Changes since v2:

  The kernel test robot <lkp@intel.com> found the same error using
  scripts/coccinelle/tests/odd_ptr_err.cocci and
  Julia Lawall <julia.lawall@inria.fr> sent us a patch, but nothing
  changed because that error was already fixed in v2.

Changes since v3:

  Reduce lines changed in drivers/usb/usbip/stub_dev.c .
  Split into 12 patches.

Tetsuo Handa (12):
  usb: usbip: introduce usbip_event_mutex for serialization
  usb: usbip: vhci: serialize attach_store()/detach_store() against event_handler()
  usb: usbip: vudc: serialize usbip_sockfd_store() against event_handler()
  usb: usbip: stub: serialize usbip_sockfd_store() against event_handler()
  usb: usbip: don't reset tcp_socket at vhci_device_reset()
  usb: usbip: fix error handling of kthread_get_run()
  usb: usbip: preallocate kernel threads for consistent attach operation
  usb: usbip: check that stream socket is used
  usb: usbip: vhci: add automatic recovery to attach_store()
  usb: usbip: vudc: add automatic recovery to usbip_sockfd_store()
  usb: usbip: stub: add automatic recovery to usbip_sockfd_store()
  usb: usbip: remove unused kthread_get_run()
