I would recommend to merge this with the 05/13 patch that is setting the btrfs
fe_physical_length field. Otherwise, by itself it would be confusing that the
DATA_COMPRESSED flag is set on the extent without fe_physical_length being set
to be able to do anything with that information.

Cheers, Andreas
