Hi,
I am very new in kernel stuff, so I dont know if it is a feature or
a some kind of bug, but using several line code one can somhow hide a
proces. The process is not visible for any known me ps tool.=20
If I lode the module:

struct task_struct * task;
task=3Dfind_task_by_pid(<pid>);
task->pid=3D0;

I can not see this task using ps, top, pstree but it is running.=20
I know that if one is able to load modules one can do a lot,
but I was just suprise that it is so simple.=20

Perhaps it will cause problems letter but now it works.=20

Best regards
Lukasz
