LogFS for F11-XO-1?

LogFS is getting merged into linux-next -
http://lwn.net/Articles/363572/ - . The author claims 60ms mount time
on our XO-1
 - http://lwn.net/Articles/234441/ - and it has several nice things
(ie: compression is per file / directory, set with chattr).

This used to be very hard -- but we now have partitioned image support
in our build toolchain and boot process, so as long as we can get the
right kmods in the initramfs, we can boot (and experiment) with
filesystems without having to implement FS support in OFW.

Would be interesting to see what the performance & stability is.

If it works, buried in the patchseries announcement there is a hint at
support for async ops. Hard to know how it'd interact with the timings
of our CaFe, but it could be interesting to retry the async patch.
