Subject[PATCH v2 3/6] selftests: breakpoints: do not use ksft_exit_skip after ksft_set_plan
Date
Calling ksft_exit_skip after ksft_set_plan results in executing fewer tests
than planned. Use ksft_test_result_skip for the individual tests.
The call in suspend() is fine, but ksft_set_plan should be after it.
