[PATCH v1 0/2] DAC,SELinux: do not remember/recall labels for

Libvirt is trying to do multiple open() calls in /dev/vfio files, which results in errors inside the security drivers and QEMU returning error 125 when attempting to hotplug a hostdev which belongs to the same IOMMU group as an existing domain hostdev. See patch 2 commit msg for more details. I found this problem when testing a PCI multifunction hotplug implementation. Since this is a problem that can happen in other currently supported scenarios, I decided it was worth sending the fix right away. Michal, I'm CCing you because I mentioned commit 4e95cdcbb3 ("security: Don't remember labels for TPM") in patch 2, which seems to fix a very similar problem. Figured you might want to take a look.
