  "message": "[PATCH] ITIMER_REAL: fix possible deadlock and race\n\nAs Steven Rostedt pointed out, there are 2 problems with ITIMER_REAL\ntimers.\n\n1. do_setitimer() does not call del_timer_sync() in case\n   when the timer is not pending (it_real_value() returns 0).\n   This is wrong, the timer may still be running, and it can\n   rearm itself.\n\n2. It calls del_timer_sync() with tsk-\u003esighand-\u003esiglock held.\n   This is deadlockable, because timer\u0027s handler needs this\n   lock too.\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
