From f58746bd33f28bc7625e4fd6b166b6f977253c7d Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Wed, 19 Aug 2015 17:22:26 +0200 Subject: libpayload: Fix default_memmove() implementation If I wanted to fill the whole memory address space with one byte, I wouldn't try it that subtle. With size_t beeing unsigned the loop condition >= 0 was always true.
