move daemonized kernel threads into the swapper's session
Daemonized kernel threads run in the init's session. This doesn't match the behaviour of kthread_create()'ed threads, and this is one of the 2 reasons why we need a special hack in sys_setsid(). Now that set_special_pids() was changed to use struct pid, not pid_t, we can use init_struct_pid and set 0,0 special pids. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: "Eric W.
