    How to suspend a task from a kernel module


    I'm trying to write a kernel module to stop users from using more than a certain percentage of CPU.
    I managed to calculate what percentage of CPU each user is using on the system but I can't find a way to suspend their processes (and later on resume then) when they have reached their threshold.

    I have the "struct task_struct *p" for each process I want to suspend. I tried changing p->state or p->time_slice but it doesn't work and I can't find a clear way to stop the process from running.

    Any idea ?

    Thanks in advance,

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Try these Google search terms - a lot of links with relevant information show up: linux kernel suspend task
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!
