Description of problem:
gnbd and device-mapper-multipath do not work well together. GNBD devices that
should not be monitored are being monitored by multipathd, and some gnbd devices
that should be monitored are not.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.service multipathd start
3.gnbd_import -i <gnbd_server>

There are small fixes necessary for both gnbd and device-mapper-multipath. I
already have the code done and tested.
Devel ACK for beta2 - regression from rhel4.
