2680 * back to userspace, we'll need to fiddle with USB devio internals
2681 * and/or reimplement entirely the frontend of it ourselves. -DaveM
2682 *
2683 * The issue is:
2684 *
2685 * When an URB is submitted via usbdevicefs it is put onto an
2686 * asynchronous queue. When the URB completes, it may be reaped
2687 * via another ioctl. During this reaping the status is written
2688 * back to userspace along with the length of the transfer.
2689 *
2690 * We must translate into 64-bit kernel types so we pass in a kernel
2691 * space copy of the usbdevfs_urb structure. This would mean that we
2692 * must do something to deal with the async entry reaping. First we
2693 * have to deal somehow with this transitory memory we've allocated.
2694 * This is problematic since there are many call sites from which the
2695 * async entries can be destroyed (and thus when we'd need to free up
2696 * this kernel memory). One of which is the close() op of usbdevicefs.
2697 * To handle that we'd need to make our own file_operations struct which
2698 * overrides usbdevicefs's release op with our own which runs usbdevicefs's
2699 * real release op then frees up the kernel memory.
2700 *
2701 * But how to keep track of these kernel buffers? We'd need to either
2702 * keep track of them in some table _or_ know about usbdevicefs internals
2703 * (ie. the exact layout of its file private, which is actually defined
2704 * in linux/usbdevice_fs.h, the layout of the async queues are private to
2705 * devio.c)
2706 *
2707 * There is one possible other solution I considered, also involving knowledge
2708 * of usbdevicefs internals:
2709 *
2710 * After an URB is submitted, we "fix up" the address back to the user
2711 * space one. This would work if the status/length fields written back
2712 * by the async URB completion lines up perfectly in the 32-bit type with
2713 * the 64-bit kernel type. Unfortunately, it does not because the iso
2714 * frame descriptors, at the end of the struct, can be written back.
2715 *
2716 * I think we'll just need to simply duplicate the devio URB engine here.
