From 6573369dd735c43930bfddec34124da05b1584df Mon Sep 17 00:00:00 2001 From: Jincheng Miao Date: Wed, 10 Dec 2014 11:33:01 +0800 Subject: [PATCH] igb_uio: fix build with kernel 3.18 From upstream kernel commit 3db2e9cd, strict_strto* serial functions are removed. So that we should directly used kstrtoul instead. kstrtoul exists from RHEL6.4, so for compatibility with old kernel and RHEL, add some logic to igb_uio/compat.h.
