Subject: [PATCH 0/7] tracing: Fix bugs in string filters.
Date: Mon, 14 Dec 2009 11:57:11 +0800 [thread overview]
Message-ID: <4B25B797.1040201@cn.fujitsu.com> (raw)
This patchset fixes some bugs in string filters.
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().
