From 091bb8ab51c668635d1a75359019005921676881 Mon Sep 17 00:00:00 2001 From: roel kluin Date: Fri, 23 Oct 2009 05:21:56 +0000 Subject: [PATCH] net: Cleanup redundant tests on unsigned If there is data, the unsigned skb->len is greater than 0. rt.sigdigits is unsigned as well, so the test `>= 0' is always true, the other part of the test catches wrapped values.
