4 UAPI Checker
7 The UAPI checker (``scripts/check-uapi.sh``) is a shell script which
8 checks UAPI header files for userspace backwards-compatibility across
14 This section will describe the options with which ``check-uapi.sh``
19 check-uapi.sh [-b BASE_REF] [-p PAST_REF] [-j N] [-l ERROR_LOG] [-i] [-q] [-v]
23 -b BASE_REF Base git reference to use for comparison. If unspecified or empty,
24 will use any dirty changes in tree to UAPI files. If there are no
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).
