  rpc_pipe: expand the calls of rpc_mkdir_populate()
  rpc_gssd_dummy_populate(): don't bother with rpc_populate()
  rpc_mkpipe_dentry(): switch to simple_start_creating()
  rpc_pipe: saner primitive for creating regular files
  rpc_pipe: saner primitive for creating subdirectories
  rpc_pipe: don't overdo directory locking
  rpc_mkpipe_dentry(): saner calling conventions
  rpc_unlink(): saner calling conventions
  rpc_populate(): lift cleanup into callers
  rpc_unlink(): use simple_recursive_removal()
