I think the use of "tree" in the XATTR description is a bit misleading. It doesn't really matter how the xattrs are layed out on disk, or how they are addressed internally to the filesystem. The "extents" returned by FIEMAP will just be a list of {physical,logical start}+length ranges that map one (or more) locations on disk the xattrs for this inode are stored.
