From 9dd4ca470e03334f95cc96529ba090921aac8eab Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 16 Jun 2017 11:39:15 -0300 Subject: tools: Adopt noinline from kernel sources To have a more compact way to ask the compiler not to inline a function and to make tools/ source code look like kernel code.
