[libvirt PATCH v6 15/30] nodedev: add function to generate mdevctl define command
Jonathon Jongsma

Fri Mar 26 16:48:11 UTC 2021
Abstract out the function used to generate the commandline for 'mdevctl
start' since they take the same arguments. Add tests to ensure that
we're generating the command properly.
