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.

Hope this helps,
