Subject: [PATCH] [PATCH] session_of_pgrp: kill unnecessary
 do_each_task_pid(PIDTYPE_PGID)

All members of the process group have the same sid and it can't be == 0.

NOTE: this code (and a similar one in sys_setpgid) was needed because it
was possibe to have ->session == 0. It's not possible any longer since

	[PATCH] pidhash: don't use zero pids
