Allison Henderson says:

====================
selftests: rds: add config file and config.sh -c option

This series adds an RDS-specific config file for ksft CI and extends
config.sh with a -c flag to specify an alternate config file path.
Users can now specify the path of the config they want to update, or
default to .config if none is specified.
