From: Stephen Hemminger Date: Fri, 2 May 2014 23:42:53 +0000 (-0700) Subject: eal: don't inline string functions X-Git-Tag: spdx-start~10820 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e5ac7c2ff367edd;p=dpdk.git eal: don't inline string functions It makes no sense to inline string functions, in fact snprintf can't be inlined because the function supports variable number of arguments.
