Subject: s390/qeth: when thread completes, wake up all waiters
From: Julian Wiedmann <jwi@linux.vnet.ibm.com>
[ Upstream commit 1063e432bb45be209427ed3f1ca3908e4aa3c7d7 ]
qeth_wait_for_threads() is potentially called by multiple users, make
sure to notify all of them after qeth_clear_thread_running_bit()
adjusted the thread_running_mask. With no timeout, callers would
otherwise stall.
