Btrfs devel - Jun 2012 - PATCH: btrfs defrag ioctl, override extent count and size checks compression enabled.

I noticed a few days ago that btrfs fi defrag -cXXX can not be used to
compress files unless they are fragmented. The attached patch passes
the compression flag to should_defrag_range, where it disables the
adjacent-extent and extent size checks if set. The inline/sparse
extent check is not modified - I assumed it would not be useful to
compress inline extents.
