I'm still unconvinced that this is anywhere close to correct.

Look.  DMA engines only automatically unmap when they're being used by the
async_tx stuff for memcpy's, and RAID computation offload, and the like.
These work with individual single buffers, not scatterlists.  These will
not be fragmented.

Got it. You are right.

@Vinod: Please drop this patch.
