Christoph Hellwig d152c682f0 block: add an explicit ->disk backpointer to the request_queue ... Replace the magic lookup through the kobject tree with an explicit backpointer, given that the device model links are set up and torn down at times when I/O is still possible, leading to potential NULL or invalid pointer dereferences.
