Re: kern/28448 (stackable filesystems locking breakage when looking up DOTDOT)

Synopsis: stackable filesystems locking breakage when looking up DOTDOT

I don't understand the problem.  There are two cases:

1) the lower layer exports a lock and there is no upper lock
2) the lower layer does not export a lock pointer, in which case the
   relock dance in the lower layer will not use the upper layer's

Either way I don't see a deadlock between the lower and upper layer.
