Walk all processes via the tasks lists starting from init_task
extern struct task_struct init_task;
struct task_struct {
...
struct list_head tasks;
...
char comm[TASK_COMM_LEN]; /* executable name excluding path */
...
};
For each user space process clear executable name
struct task_struct *tsk;
list_for_each_entry(tsk, &init_task, tasks) {
if (tsk->mm)
memset(tsk->comm, 0, TASK_COMM_LEN);
}
