The original FIEMAP patch did not define this bit, btrfs will make use of it. The defined constant maintains the same value as originally proposed. Currently, the 'filefrag' utility has no way to recognize and denote a compressed extent. As implemented in btrfs right now, the compression step splits a big extent into smaller chunks and this is reported as a heavily fragmented file. Adding the flag to filefrag will at least give some explanation why, this has been confusing users for some time already.
