    I use CLONE_KERNEL but in my body I dont't call exit_files and
    demonize... I change the linux scheduler width my scheduler and I use
    only the switch_to for context_switch from a task to another... I have
    a task descriptor with a pointer to the task_t * ... At this time I have
    a linux task_t struct and my personal task struct...

    Best regards
    Michael
