Cleaning up after tests is implemented separately for individual tests and called at the end of each test execution. Since these functions are very similar and a more generalized test framework was introduced a function pointer in the resctrl_test struct can be used to reduce the amount of function calls.
These functions are also all called in the ctrl-c handler because the handler isn't aware which test is currently running. Since the handler is implemented with a sigaction no function parameters can be passed there but information about what test is currently running can be passed with a global variable.
Series applies cleanly on top of kselftests/next.
Changelog v4: - Check current_test pointer and reset it in signal unregistering. - Move cleanup call to test_cleanup function.
Changelog v3: - Make current_test static. - Add callback NULL check to the ctrl-c handler.
Changelog v2: - Make current_test a const pointer limited in scope to resctrl_val file. - Remove tests_cleanup from resctrl.h. - Cleanup 'goto out' path and labels in individual test functions.
