The other functions which are in the critical section are getting inlined so I have used _raw_spin_lock_irqsave to write the selftests. Other approach could be to just pass the tests if the function is getting inlined just like in https://elixir.bootlin.com/linux/latest/source/tools/testing/selftests/bpf/prog_tests/htab_update.c
