Thank you everyone who gave a tag to this.

I'm going to split and rebase on top of Christoph's branch
http://git.infradead.org/users/hch/vfs.git/shortlog/refs/heads/uuid-type
s

followed by changing types and API calls accordingly (without changing a
logic!).

So, I would like to keep tags in place. If there is any objection, speak
up now!

Thanks!
