Subject: [PATCH 2/3] Drivers: hv: vmbus: Treat Fibre Channel devices as performance critical
Date: Tue, 15 Dec 2015 16:27:27 -0800	[thread overview]
Message-ID: <1450225648-4711-2-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1450225648-4711-1-git-send-email-kys@microsoft.com>

For performance critical devices, we distribute the incoming
channel interrupt load across available CPUs in the guest.
Include Fibre channel devices in the set of devices for which
we would distribute the interrupt load.
