I've also pushed out a tree based on this, which contains my little
fixups that I'd suggest to be folded. Totally untested and written
while jetlagged:

http://git.infradead.org/users/hch/block.git/shortlog/refs/heads/io_uring-passthrough

Note that while I tried to keep all my changes in separate patches, the
main passthrough patch had conflicts during a rebase, which I had to
fix up, but I tried to touch as little as possible.
