Subject: [PATCH 0/7][RESEND] tracing: Fix bugs in string filters.
Date: Thu, 14 Jan 2010 10:52:43 +0800	[thread overview]
Message-ID: <4B4E86FB.40208@cn.fujitsu.com> (raw)

This patchset fixes some bugs in string filters. Those bugs
affect both ftrace and perf-trace.

A new string helper strnstr() is introduced, to be used in
middle matching callback.

Also I add some comments to mainly explain why we should use
length-limited version of strstr() and strcmp().
