Due to a coincidence I yesterday took a quick look myself and didn't
spot anything. But in case you haven't looked further: I found one in
the SLE-Kernels:

http://kernel.opensuse.org/cgit/kernel-source/tree/patches.suse/btrfs-8888-add-allow_unsupported-module-parameter.patch?h=SLE11-SP3

P.S.: BTW, Jeff Mahoney a year ago posted a small table what btrfs
features they considered supported and unsupported:
http://thread.gmane.org/gmane.linux.suse.opensuse.devel/52669/
Is anyone aware of a more current table like that? Or Josef, do the
Btrfs developers maintain one somewhere? I'd welcome one.
