[Cluster-devel] [DLM PATCH] dlm_controld: add option of enable_force_kick

When there are 3 or more partitions that merge, none may see enough clean nodes. Therefore, DLM would be stuck there forever unitl administrator manually reset/restart enough nodes to produce sufficient clean nodes. However, sometimes people hope that DLM can automatically recover from "useless"
