Subject: [PATCH 4.4 15/20] s390/qeth: when thread completes, wake up all waiters
Date: Thu, 29 Mar 2018 20:00:51 +0200 [thread overview]
Message-ID: <20180329175742.647123546@linuxfoundation.org> (raw)
In-Reply-To: <20180329175741.886181131@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
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.
