From 5ecaafdbf44b1ba400b746c60c401d54c7ee0863 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Fri, 5 Feb 2010 01:24:34 -0500 Subject: [PATCH] kprobes: Add mcount to the kprobes blacklist Since mcount function can be called from everywhere, it should be blacklisted. Moreover, the "mcount" symbol is a special symbol name. So, it is better to put it in the generic blacklist.
