I have Debian/Wheezy systems that are running BTRFS without problems and I
don't think there's any need for an upgrade.

Like I mentioned before, in Marc Merlin talk at LCA2015, is specifically recommends against using kernels 3.15 to 3.16.1 - Debian Jessie has 3.16.0...

I personally would be nervous about going against Marc's recommendations here.

Unless of course the Debian kernel has fixes back ported.
