Re: [PATCH] jffs2: remove redundant check on outpos > pos

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

The check for outpos > pos is always false because outpos is zero
and pos is at least zero; outpos can never be greater than pos.
The check is redundant and can be removed.

Maybe this check could detect the overflow of 'pos', I guess.
-	if (outpos > pos) {
-		/* We failed */
-		return -1;
-	}

  	/* Tell the caller how much we managed to compress,
  	 * and how much space it took */
