There are races where the receiver may be exiting, but still need the worker to process some stuff. Do not wait for the receiver to die from an exiting worker. The receiver must already be dead in case the worker decides to exit. If the receiver was still alive, it may still want to queue work, and do drbd_flush_workqueue() from it's disconnect cleanup code, which would no longer be processed by an exiting worker. This also would deadlock, if the worker was to synchornously wait for the receiver to die. Do not implicitly stop the worker. The worker will only be stopped from configuration context, from conn_reconfig_done(), drbd_adm_down() or drbd_adm_delete_connection(), after making sure the receiver is already stopped.
