Let me try to re-stoke your enthusiasm a bit :)

If you are comfortable with patching your own kernel you can take
a look at my custom patch queue, which I just put up at:
https://github.com/hhoffstaette/kernel-patches/tree/master/3.14
You can take only what you need, i.e. btrfs-*.

These are meant to be ironed over latest stable in order. and mostly
address "corner cases" that seem to happen infrequently, but still
are bad enough to leave a bad taste.

Unfortunately the btrfs code has changed significantly with 3.15+,
so later patches often no longer apply at all. However the ones that do
have been working well for me. I don't just blindly add them, but rather
at least try to understand what they do/change.

I sent out an email for comments about backporting this select set of
patches to 3.14, but got no replies. :(
