All these pieces Josh mentioned are already in the tree. I found this new line, and saw btrfs was not listed in it so added there also. The btrfs support in yocto is working with Linux-yocto 3.x kernel. The btrfs kernel config needs to be enabled, I have sent a patch for that implementing it as a kernel feature, Once that is there then also need to enable the btrfs feature in the Linux-yocto kernel recipe. I will send a patch for that too. 

Thanks,
Nitin
