Hi Ted, this commit shows up twice in the ext4 tree, as 173b8439e1ba3 and
a7ede371cb821, but the second actually adds the check two *more* times to
ext4_cross_rename(), such that there are now a total of three checks in that
function, all the same.  Do you want to revert the second, unnecessary, commit?

Thanks,

Eric
