From: Jeff Mahoney <[email protected]> When repairing a file system created by a very old kernel, I ran into issues fixing up the extent flags since fixup_extent_flags assumed that a METADATA_ITEM would be present if the record was for metadata.
Since METADATA_ITEMs don't exist without skinny metadata, we need to fall back to EXTENT_ITEMs. This also falls back to EXTENT_ITEMs even with skinny metadata enabled as other parts of the tools do.
