From ffe11cfb0a808ae514193438616dfabc512b4cf6 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Thu, 14 Aug 2008 16:25:25 +0100 Subject: [lib] hash compare function arguments ought to be const qualified 2008-08-14 Stephen Hemminger * lib/hash.h: (struct hash) Hash comparator callback really ought to treat storage behind arguments as constant - a compare function with side-effects would be evil. * */*.c: Adjust comparator functions similarly, thus fixing at least a few compiler warnings about const qualifier being dropped.
