From 58af3110a7c5d161f72f94a98c6f2b9b75bf5cf9 Mon Sep 17 00:00:00 2001 From: Daniel Verkamp Date: Mon, 12 Nov 2018 15:22:17 -0800 Subject: lib/raid6: avoid __attribute_const__ redefinition This is defined in glibc's sys/cdefs.h on my system with the same definition as the raid6test fallback definition. Add a #ifndef check to avoid a compiler warning about redefining it.
