Subject: [PATCH v2 0/2] selftests/ftrace: Add tests for kprobes and optimized probes 

This patchset adds a stress test for kprobes and a test for checking
optimized probes.
The two tests are being added based on the below discussion:
https://lore.kernel.org/all/20230128101622.ce6f8e64d929e29d36b08b73@kernel.org/

Changelog:

* Add an explicit fork after enabling the events ( echo "forked" )
* Remove the extended test from multiple_kprobe_types.tc which adds 
  multiple consecutive probes in a function and add it as a 
  separate test case. 
* Add new test case which checks for optimized probes.
