Hi,

same thing, no success  :-(


I've checked out this tree:

git clone 
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git

The version show me "3.6.0+"

I took my  original Fedora Kernel-config to compile (btrfs as module)

[root@z2 alfred]# modinfo btrfs
filename:       /lib/modules/3.6.0+/kernel/fs/btrfs/btrfs.ko
license:        GPL
alias:          devname:btrfs-control
alias:          char-major-10-234
depends:        libcrc32c,zlib_deflate
intree:         Y
vermagic:       3.6.0+ SMP mod_unload
