That's what I assumed, however, I'm running into the same problem as with dma-sg when I switch to vmalloc...?
I've sent a "proper" patch submission again, which has all the other issues from the previous submission fixed. I'm hoping you can maybe have a closer look and see if I'm doing anything subtly wrong which causes both vmalloc and dma-sg to fail while dma-contig works.
