[Bug tapsets/4727] New: Userspace stack traceback

[wcohen at redhat dot com]

For application tuning it would be very useful to have a traceback of the
user-space stack to determine how a particular systemcall is being invoked. The
application in mind would be for looking at lock contention issues. The futext
example on the wiki points out which futexes have problems:

However, it doesn't show where in the code those are being triggered. The stack
backtrace of the user process would give developer some idea whether to look in
the code.
