From 4b1391cc3a879f4a82510742d0f1dc668d23de94 Mon Sep 17 00:00:00 2001 Message-Id: <4b1391cc3a879f4a82510742d0f1dc668d23de94@dist-git> From: John Ferlan Date: Thu, 9 Jul 2015 08:28:58 -0400 Subject: [PATCH] RHEL: qemu: Add check for unpriv sgio for SCSI generic host device https://bugzilla.redhat.com/show_bug.cgi?id=1072736 RHEL-only Check if the hostdev has set the sgio filtered/unfiltered and handle appropriately. This restores functionality removed by upstream commit id 'ce346623' to remove sgio support for the SCSI generic host device.
