Return-Path: From: Julian Wiedmann Subject: [PATCH net 2/4] s390/qeth: when thread completes, wake up all waiters Date: Tue, 20 Mar 2018 07:59:13 +0100 In-Reply-To: <20180320065915.62076-1-jwi@linux.vnet.ibm.com> References: <20180320065915.62076-1-jwi@linux.vnet.ibm.com> Message-Id: <20180320065915.62076-3-jwi@linux.vnet.ibm.com> Sender: netdev-owner@vger.kernel.org List-Archive: List-Post: To: David Miller Cc: netdev@vger.kernel.org, linux-s390@vger.kernel.org, Martin Schwidefsky , Heiko Carstens , Stefan Raspl , Ursula Braun , Julian Wiedmann List-ID: 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.
