Subject: [PATCH net 2/4] s390/qeth: when thread completes, wake up all waiters
Date: Tue, 20 Mar 2018 07:59:13 +0100 [thread overview]
Message-ID: <20180320065915.62076-3-jwi@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180320065915.62076-1-jwi@linux.vnet.ibm.com>
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.
