From d3dbd93db54f477e066926394e3e4ae3ac06cd3b Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Fri, 19 Jul 2013 16:20:15 +0900 Subject: xen: replace strict_strtoul() with kstrtoul() The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used.
