    kernel - Refactor vfs_cache 3/N
    
    * Leave the vnode held for each linked namecache entry, allowing us to
      remove all the hold/drop code for 0->1 and 1->0 lock transitions of
      ncps.
    
      This significantly simplifies the cache_lock*() and cache_unlock()
      functions.
    
    * Adjust the vnode recycling code to check v_auxrefs against
      v_namecache_count instead of against 0.
