I don't understand what is expected. The only place where EINTR is used is in
raw_write file io/unix.c with a comment

  /* We must write in a loop since some systems don't restart system
     calls in case of a signal.  */

For raw_read, the comment is

  /* For read we can't do I/O in a loop like raw_write does, because
     that will break applications that wait for interactive I/O.  */
