Для /proc'а смотрите функцию get_tid_list() там нужно
вставить что-то типа:
if (task->euid != current->euid &&
task->egid != current->egid)
continue;

и примерно такой же код в proc_pid_lookup()

но это только чтобы ps и top не показывали чужие процессы.
Секьюрности это мало добавляет Smile

))

Более сложные вещи надо обдумывать...
