[libvirt] [PATCH v3 0/6] Work around the kernel mdev uevent race in nodedev

v2 here: https://www.redhat.com/archives/libvir-list/2017-July/msg01268.html Since v2: - added patch 4/6 that fixes the issue with the handler thread spamming logs with "udev_monitor_receive_device returned NULL" -> the event loop callback now disables polling on the udev monitor's fd every time there's a new event, leaving the responsibility for re-enabling it back to the handler thread once it had removed the corresponding data from the socket.
