[PATCH v3 0/2] selftests/ftrace: Add tests for kprobes and optimized probes

[Akanksha J N]

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@xxxxxxxxxx/
kprobe_opt_types.tc is modified as per the below review comments:
https://lore.kernel.org/all/1682506809.uus6y0ir3i.naveen@xxxxxxxxxxxxx/#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.
