[PATCH net 2/4] s390/qeth: when thread completes, wake up all waiters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
