[Qemu-devel] [PULL 04/18] vfio: Fix broken EEH

From: David Gibson
Subject: [Qemu-devel] [PULL 04/18] vfio: Fix broken EEH
Date: Fri, 17 Jun 2016 16:36:25 +1000

From: Gavin Shan <address@hidden>

vfio_eeh_container_op() is the backend that communicates with
host kernel to support EEH functionality in QEMU. However, the
functon should return the value from host kernel instead of 0

dwg: Specifically the problem occurs for the handful of EEH
sub-operations which can return a non-zero, non-error result.
