I've changed the description of this commit to reflect the change in
how I propose to fix the problem....

commit 8d12c46a22965179cae1e3b47778fdee5efeb513
Author: Tao Ma <boyu.mt@xxxxxxxxxx>

tests: add new test f_zero_extent_length
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.
