Subject: [PATCH 00/11] tracing: bugfix and kprobe-based dynamic event updates
Date: Thu, 09 May 2013 14:44:05 +0900	[thread overview]
Message-ID: <20130509054405.30398.73831.stgit@mhiramat-M0-7522> (raw)

Hi,

Here is a series of updating kprobe-based dynamic event for
supporting soft-disabling mode and multiple buffers.
This also has some bugfixes of ftrace which I found
including an important deadlock fix.

I think uprobe-based events can also support multi-buffer
and soft-disabling as I did in this series.
