From 13966721a11f4a2ba8038191e48083b5f31822bb Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Thu, 6 Jun 2013 14:35:03 +0300 Subject: [PATCH] perf bench: Fix memory allocation fail check in mem{set,cpy} workloads Addresses of allocated memory areas saved to '*src' and '*dst', so we need to check them for NULL, not 'src' and 'dst'.
