C Comment in Emacs - Linux Kernel Style

(setq-default comment-style 'multi-line)

and comments in my region on execution M-;:

/* void main()
 * {
 *  int i;
 *  int b;
 *  printf("format string");
 * } */

But I want them to look like this:

/* 
 * void main()
 * {
 *  int i;
 *  int b;
 *  printf("format string");
 * }
 */

What do i need to change?
