  "message": "[PATCH] pids: kill PIDTYPE_TGID\n\nThis patch kills PIDTYPE_TGID pid_type thus saving one hash table in\nkernel/pid.c and speeding up subthreads create/destroy a bit.  It is also a\npreparation for the further tref/pids rework.\n\nThis patch adds \u0027struct list_head thread_group\u0027 to \u0027struct task_struct\u0027\ninstead.\n\nWe don\u0027t detach group leader from PIDTYPE_PID namespace until another\nthread inherits it\u0027s -\u003epid \u003d\u003d -\u003etgid, so we are safe wrt premature\nfree_pidmap(-\u003etgid) call.\n\nCurrently there are no users of find_task_by_pid_type(PIDTYPE_TGID).\nShould the need arise, we can use find_task_by_pid()-\u003egroup_leader.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-By: Eric Biederman \u003cebiederm@xmission.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
