    VFS accounting: do not count write operations for removed files
    
    * vnode operations can and do happen out-of-order in some circumstances
      (multi-job builds with make for example)
    
    * check if the vnode has at least one associated link to be sure it
      still corresponds to an existing file
    
    * do not count the write operation if this is not the case
