23 -b BASE_REF Base git reference to use for comparison. If unspecified or empty,
26 -p PAST_REF Compare BASE_REF to PAST_REF (e.g. -p v6.1). If unspecified or empty,
29 -j JOBS Number of checks to run in parallel (default: number of CPU cores).
30 -l ERROR_LOG Write error log to file (default: no error log is generated).
31 -i Ignore ambiguous changes that may or may not break UAPI compatibility.
