Yes, it's not that complicated. Looks good. BTW: You don't need the km_types voodoo as the conversion routine is never called from a softirq context and you are allowed (but should try to avoid it) to sleep. You could add a conditional reschedule after kunmapping the buffers to keep the latency low on non-preempt kernels.
BTW: I've got some cleanups and a small fix in Andrew's latest tree (using a #define for the log prefix and I bvec array thingy).
