  "message": "posix timers: release_posix_timer: kill the bogus put_task_struct(-\u003eit_process);\n\nrelease_posix_timer() can\u0027t be called with -\u003eit_process !\u003d NULL.  Once\nsys_timer_create() sets -\u003eit_process it must not call\nrelease_posix_timer(), otherwise we can race with another thread doing\nsys_timer_delete(), this timer is visible to idr_find() and unlocked.\n\nThe same is true for two other callers (actually, for any possible\ncaller), sys_timer_delete() and itimer_delete().  They must clear\n-\u003eit_process before unlock_timer() + release_posix_timer().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\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",
