I'd turn it into a patch for the drivers/block/ directory and submit it to the people that scripts/get_maintainer.pl says to use. Also cc: the linux-fsdevel mailing list as the developers there might be able to help out on the block dma issues. I can always put it in the drivers/staging/ directory today, but I don't see any reason it shouldn't just go into the main part of the kernel instead.
