From 1eff1ad0285038e309a81da4a004f071608309fb Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Wed, 16 Feb 2011 16:26:44 -0500 Subject: xen/irq: The Xen hypervisor cleans up the PIRQs if the other domain forgot. And if the other domain forgot to clean up its PIRQs we don't need to fail the operation. Just take a note of it and continue on.
