    Useless checks ?
    Correct me if I'm wrong !

    In include/linux/sched.h for_each_task is
    defined as :

            #define for_each_task(p) \
                    for (p = &init_task ; (p = p->next_task) != &init_task ; )

    So p can't be init (pid 1),but in
    several files i discoverd a check if p is init.

    So please check the files :

    file:line

    drivers/char/sysrq.c:44
    fs/proc/base.c:983
    kernel/signal.c:543
    kernel/capability.c:109
