Thanks to everyone that tried out btrfs. Most of those that did managed
to hit problems with apps that did writes via mmap. So, I added a
page_mkwrite call and worked out cow safe mmap writes.

Terje Røsten sent along a btrfsprogs patch so that it compiles properly
on FC7 (thanks!).

I'll have a site up on with mailing lists and
links to my HG trees shortly. Until then: has the latest tar balls.
