dma-api is request-oriented (the API is called to set up and tear down a 
single dma request), while the kvm usage is address space oriented (the 
API is called to set up, maintain, and tear down an address space, over 
which many dma requests can run).  Perhaps someone can come up with 
names that reflect that.
