Could we kill the process instead? If a process has been forced to run on a certain cpu then it is an error to migrate it to a different one. If a system wiil do cpu hot remove then the system needs to be configured in such a way as to allow processes to be migrated to other processors. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
