  "message": "[PATCH] find_task_by_pid() needs tasklist_lock\n\nA couple of places are forgetting to take it.\n\nThe kswapd case is probably unimportant.  keventd_create_kthread() was racy.\n\nThe whole thing is a bit flakey: you start a kernel thread, get its pid from\nkernel_thread() then look up its task_struct.\n\na) It assumes that pid recycling takes a \"long\" time.\n\nb) We get a task_struct but no reference was taken on it.  The owner of the\n   kswapd and kthread task_struct*\u0027s must assume that the new thread won\u0027t\n   exit unexpectedly.  Because if it does, they\u0027re left holding dead memory\n   and any attempt to control or stop that task will crash.\n\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
