From d45d23bed4bf7b25b7dcc336552a251db1aa1279 Mon Sep 17 00:00:00 2001 From: Robert Richter Date: Tue, 16 Dec 2008 12:00:10 +0100 Subject: oprofile: add inline function __oprofile_add_ext_sample() This patch adds the inline function __oprofile_add_ext_sample() to cpu_buffer.c and thus reduces overhead when calling oprofile_add_sample().
