  Log:
   - Reorder calls to vrele() after calls to vput() when the vrele is a
     directory.  vrele() may lock the passed vnode, which in these cases would
     give an invalid lock order of child -> parent.  These situations are
     deadlock prone although do not typically deadlock because the vrele
     is typically not releasing the last reference to the vnode.  Users of
     vrele must consider it as a call to vn_lock() and order it appropriately.
