The benchmark command handling (-b) in resctrl selftests is overly complicated code. This series turns the benchmark command immutable to preserve it for all selftests and improves benchmark command related error handling.
This series also ends up removing the strcpy() calls which were pointed out earlier.
v4: - Correct off-by-one error in -b processing - Reordered code in main() to make freeing span_str simpler (in new patch) - Use consistent style for const char * const *
v3: - Removed DEFAULT_SPAN_STR for real and the duplicated copy of defines that made to v2 likely due to my incorrect conflict resolutions
v2: - Added argument length check into patch 1/7 - Updated also -b line in help message. - Document -b argument related "algorithm" - Use asprintf() to convert defined constant int to string - Improved changelog texts - Added \n to ksft_exit_fail_msg() call messages. - Print DEFAULT_SPAN with %u instead of %zu to avoid need to cast it
