Subject: [PULL 6/8] KVM: async_pf: Allow to wait for outstanding work
Date: Thu, 30 Jan 2014 13:53:47 +0100 [thread overview]
Message-ID: <1391086429-43935-7-git-send-email-borntraeger@de.ibm.com> (raw)
In-Reply-To: <1391086429-43935-1-git-send-email-borntraeger@de.ibm.com>
From: Dominik Dingel <dingel@linux.vnet.ibm.com>
On s390 we are not able to cancel work. Instead we will flush the work and wait for
completion.
