Subject: [PATCH v3 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/
kprobe_opt_types.tc is modified as per the below review comments:
https://lore.kernel.org/all/1682506809.uus6y0ir3i.naveen@linux.ibm.com/#t

Changelog:

v3:

* Add Acked-by for kprobe_insn_boundary.tc
* Simplify test for optimized probe, as suggested by Masami
* Add exit_unresolved to exit as unresolved in case no probe was optimized

v2:

* 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.

Akanksha J N (2):
  selftests/ftrace: Add new test case which adds multiple consecutive
    probes in a function
  selftests/ftrace: Add new test case which checks for optimized probes
