    kernel - Rejigger mount code to add vfs_flags in struct vfsops
    
    * Rejigger the mount code so we can add a vfs_flags field to vfsops,
      which mount_init() has visibility to.
    
    * Allows nullfs to flag that its mounts do not need a syncer thread.
      Previously nullfs would destroy the syncer thread after the
      fact.
    
    * Improves dsynth performance (it does lots of nullfs mounts).
