Chris Mason 7c2fe32a23 Btrfs: Fix add_extent_mapping to check for duplicates across the whole range ... add_extent_mapping was allowing the insertion of overlapping extents. This never used to happen because it only inserted the extents from disk and those were never overlapping. But, with the data=ordered code, the disk and memory representations of the file are not the same. add_extent_mapping needs to ensure a new extent does not overlap before it inserts.
