Well I was going to apply and now I have second thoughts.
The patch does describe the members, it just does not
describe them well.
for example,

there's no "mapping buffer" that needs configuration.
the type tells it all:
 * struct virtio_map_ops - operations for mapping buffer for a virtio device

this one is not a "virtual map" either.
more a "device or domain used for mapping memory"

Thanks for the suggestions! I'll apply them in v3 (should be out in Monday).
