Subject: [PATCH 0/7][RESEND] tracing: Fix bugs in string filters.
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().
