- add systemtap static markers (wcohen, mjw, dmalcolm; patch 8), a
systemtap tapset defining "python.function.entry" and
"python.function.return" to make the markers easy to use (dmalcolm;
source 5), and an example of using the tapset to the docs (dmalcolm;
source 6) (rhbz:545179)

Example usage of the Python systemtap tapset to show a nested view of all

Run this using

stap systemtap-example.stp

stap systemtap-example.stp -c COMMAND
