It renamed to cgroup before merging into mainline, and cgroup stands for control group. Cgroup provides a mechanism to divide all the processes into groups, and then a cgroup subsystem can act on groups rather than on threads. The first cgroup subsystem is cpuset which assigns a set of cpus and memory nodes to a set of processes. In fact the auther of cgroup extracted the mechanism of dividing and aggregating tasks from cpuset and made it cgroup. > What is the current status of development? > Cgroup is still under development. And we have cpuset, cpu, cpuacct, memory and device subsystems, besides these we have memrlimit subsys in -mm and other subsystems like swap subsys under development. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [EMAIL PROTECTED] Please read the FAQ at http://kernelnewbies.org/FAQ
