  MFC: New unionfs implementation from Daichi GOTO and Masanori OZAWA,
       which fixes many locking and crashing problems in the previous
       implementation.  kib@ helped a lot by eliminating a source
       of deadlocks encountered with unionfs with these commits:
         rev. 1.50 of src/sys/fs/deadfs/dead_vnops.c
         rev. 1.97 of src/sys/kern/vfs_lookup.c
