From 3fa7bf7229993eac65fd6ade2ffc5f75150b40e1 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Fri, 4 Mar 2016 10:53:13 +1100 Subject: [PATCH] powerpc/eeh: Don't remove passed VFs When we have partial hotplug as part of the error recovery on PF, the VFs that are bound with vfio-pci driver will experience hotplug. That's not allowed. This checks if the VF PE is passed or not. If it does, we leave the VF without removing it.
