| |
Add --max-file-size option (default off) to limit size of files that checkpatch processes. Such an option is useful when checkpatch is run automatically during checkins to a source control system and someone acccidently or purposely attempt to commit massive size files to the system. If the checkpatch script runs on such files it could take a long time to run and limit the server's ability to perform other operations.
