Hi, First off, I'm not sure if this is the right list to be posting on. Sorry if it isn't. I'm trying to modify the Linux scheduler by adding logic to temporarily render a cgroup to be unschedulable. One way to do this would be to take advantage of the fact that each `cgroup` has a `tasks` file that is able to list all the PIDs of that `cgroup`. Iterating over each task and setting its state to be blocked should allow me to accomplish this, but this approach has a complexity proportional to the size of the PID list. Instead, since the scheduler has notion of groups, is it possible to tell the scheduler to ignore one of the groups while looking for the next task to run?
