  "message": "uglify kill_pid_info() to fix kill() vs exec() race\n\nkill_pid_info()-\u003epid_task() could be the old leader of the execing process.\nIn that case it is possible that the leader will be released before we take\nsiglock. This means that kill_pid_info() (and thus sys_kill()) can return a\nfalse -ESRCH.\n\nChange the code to retry when lock_task_sighand() fails. The endless loop is\nnot possible, __exit_signal() both clears -\u003esighand and does detach_pid().\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: \"Eric W.
