If all of the extents in the last extent tree block (ETB) in a non-trivial extent tree contain uninitialized extents which are after the end of the file as defined by i_size, the hueristics will incorrectly estimate the last entry (and hence the node's e_len field) in the last entry of each level of the extent tree. As Tao Ma has noted, since e2fsck was requiring that the length (e_len) field of interior nodes be non-zero, this was causing false failures where e2fsck would declare that the extent tree was corrupted. This was fixed in commit 9c40d14841: "e2fsck: only check for zero-length leaf extents". Add a regression test case to ensure that this issue remains fixed.
