  "message": "fix group stop with exit race\n\ndo_signal_stop() counts all sub-thread and sets -\u003egroup_stop_count\naccordingly.  Every thread should decrement -\u003egroup_stop_count and stop,\nthe last one should notify the parent.\n\nHowever a sub-thread can exit before it notices the signal_pending(), or it\nmay be somewhere in do_exit() already.  In that case the group stop never\nfinishes properly.\n\nNote: this is a minimal fix, we can add some optimizations later.  Say we\ncan return quickly if thread_group_empty().  Also, we can move some signal\nrelated code from exit_notify() to exit_signals().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Davide Libenzi \u003cdavidel@xmailserver.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
