  Log:
   - Remove PDIRUNLOCK, it will soon be unused in every filesystems.  The only
     case where filesystems legitimately need to unlock the directory vp is
     in the DOTDOT case, which we can explicitly check for in lookup().
     Furthermore, allowing filesystems to unlock dvp can lead to lock order
     reversals in lookup() when we vrele the dvp while the child is still
     locked.
