BTW, ubifs plays funny games with i_nlink - decrements it early in
unlink/rmdir/rename and then increments it back on failure.  *If*
we really want it that way, we need to use set_nlink() there.  Frankly,
I'd rather deal with drop_nlink() after the last possible failure
exit...  Unless there are serious reasons why that wouldn't work, that is.
