It's quite common I think, e.g driver track e.g dma addr and page frag
somewhere. e.g the ring->rx_info in mlx4 driver.

It seems that I had a misunderstanding on your
previous comments. I know it's quite common for
drivers to track e.g. DMA addrs somewhere (and
I think one reason behind this is that they want
to reuse the bits of addr field). But tracking
addrs somewhere doesn't means suppor...
