Subjectdma_sync_sg_for_cpu applied to a single scatterlist element
This is addressed to James Bottomley as he is the author of
Documentation/DMA-API.txt, but anyone else who can contribute is
invited to do so.

Suppose a scatter-gather transfer with multiple scatterlist elements
has been mapped via dma_map_sg(). Is it then valid to call
dma_sync_sg_for_cpu() with the "sg" argument pointing to one of the
mapped scatterlist elements (not necessarily the first one) and the
"nelems" argument set to 1?

Thanks,

Alan Stern
