  "message": "signals: clear signal-\u003etty when the last thread exits\n\nWhen the last thread exits signal-\u003etty is freed, but the pointer is not\ncleared and points to nowhere.\n\nThis is OK.  Nobody should use signal-\u003etty lockless, and it is no longer\npossible to take -\u003esiglock.  However this looks wrong even if correct, and\nthe nice OOPS is better than subtle and hard to find bugs.\n\nChange __exit_signal() to clear signal-\u003etty under -\u003esiglock.\n\nNote: __exit_signal() needs more cleanups.  It should not check \"sig !\u003d\nNULL\" to detect the all-dead case and we have the same issues with\nsignal-\u003estats.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Alan Cox \u003calan@linux.intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nAcked-by: 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",
