To be honest, I like this series more than the previous series. I always
thought RDT_RESOURCE_L3_MON should have been a separate resource by itself.

You need to separate the domain lists for RDT_RESOURCE_L3 and
RDT_RESOURCE_L3_MON if you are going this route. I didn't see that in this
series. Also I have few other comments as well.

Thanks
