LT,
Will this maddness insure that the granularity of the request will be
dependent to the k_dev_t? Specifically, can one make KIOBUFS do the
sizing of buffer to match the ideal or specified size limits imposed by a
given block device? Otherwise I will need to design an sub-request layer

Is this use of kiobufs sensible to you ? If not, what should I really be doing
in order to acheive zero copy DMA ?
I also have a question regarding a DMA read to userspace memory :
