  "message": "kernel/pid.c: update comment on find_task_by_pid_ns\n\ntasklist_lock does protect the task and its pid, it can\u0027t go away.  The\nproblem is that find_pid_ns() itself is unsafe without rcu lock, it can\nrace with copy_process()-\u003efree_pid(any_pid).\n\nProtecting copy_process()-\u003efree_pid(any_pid) with tasklist_lock would make\nit possible to call find_task_by_pid_ns() under tasklist safely, but we\ndon\u0027t do so because we are trying to get rid of the read_lock sites of\ntasklist_lock.\n\nSigned-off-by: Tetsuo Handa \u003cpenguin-kernel@I-love.SAKURA.ne.jp\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: \"Paul E.
