3.17.3 incorporates a fix for converting ext4 to btrfs: http://git.kernel.org/cgit/linux/kernel/git/mason/btrfs-progs.git/commit/?id=ad96e8f4d656b6b46253b2122a96d5e9c4a17b18

It may help fixing the problem which I am facing since several kernel and btrs-progs releases. Never got a clean conversion from ext4 to btrfs, btrfs-progs is always complaining something is wrong. See below:

Reproducible: Always

Actual Results:  
supah ef # btrfs-convert /dev/sdb2
creating btrfs metadata.
creating ext2fs image file.
cleaning up system chunk.
conversion complete.
