[rds-devel] [External] : [PATCH net-next v2 2/2] selftests: rds: Add -c config option to rds/config.sh

[Allison Henderson]

This patch adds a new -c flag to config.sh that enables callers
to specify the file path of the config they would like to update.
If no config is specified, the default will be the .config of the
current directory.
