New Revision: 302772
URL: https://svnweb.freebsd.org/changeset/base/302772

Log:
  re-apply r299908: zfsctl_snapdir_lookup: clear VV_ROOT of snapshot's root
  
  The change has been undone in r301275 on the assumption that it was no
  longer required.  But that was incorrect, because in this case (and only
  in this case) the snapshot root vnode is looked up before z_parent is
  fixed up.
