From: Frederic Weisbecker Date: Mon, 16 Mar 2009 21:41:00 +0000 (+0100) Subject: tracing/ftrace: fix the check on nopped sites X-Git-Tag: v2.6.30-rc1~2^2~29^2~2 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=03303549b1695dc024d4a653cc16bd79f78f9750;p=karo-tx-linux.git tracing/ftrace: fix the check on nopped sites Impact: fix a dynamic tracing failure Recently, the function and function graph tracers failed to use dynamic tracing after the following commit: fa9d13cf135efbd454453a53b6299976bea245a9 (ftrace: don't try to __ftrace_replace_code on !FTRACE_FL_CONVERTED rec) The patch is right except a mistake on the check for the FTRACE_FL_CONVERTED flag. The code patching is aborted in case of successfully nopped sites. What we want is the opposite: ignore the callsites that haven't been nopped.
