2563 /* This needs more work before we can enable it. Unfortunately
2564 * because of the fancy asynchronous way URB status/error is written
2565 * back to userspace, we'll need to fiddle with USB devio internals
2566 * and/or reimplement entirely the frontend of it ourselves. -DaveM
2567 *
2568 * The issue is:
2569 *
2570 * When an URB is submitted via usbdevicefs it is put onto an
2571 * asynchronous queue. When the URB completes, it may be reaped
2572 * via another ioctl. During this reaping the status is written
2573 * back to userspace along with the length of the transfer.
2574 *
2575 * We must translate into 64-bit kernel types so we pass in a kernel
2576 * space copy of the usbdevfs_urb structure. This would mean that we
2577 * must do something to deal with the async entry reaping. First we
2578 * have to deal somehow with this transitory memory we've allocated.
2579 * This is problematic since there are many call sites from which the
2580 * async entries can be destroyed (and thus when we'd need to free up
2581 * this kernel memory). One of which is the close() op of usbdevicefs.
2582 * To handle that we'd need to make our own file_operations struct which
2583 * overrides usbdevicefs's release op with our own which runs usbdevicefs's
2584 * real release op then frees up the kernel memory.
2585 *
2586 * But how to keep track of these kernel buffers? We'd need to either
2587 * keep track of them in some table _or_ know about usbdevicefs internals
2588 * (ie. the exact layout of its file private, which is actually defined
2589 * in linux/usbdevice_fs.h, the layout of the async queues are private to
2590 * devio.c)
2591 *
2592 * There is one possible other solution I considered, also involving knowledge
2593 * of usbdevicefs internals:
2594 *
2595 * After an URB is submitted, we "fix up" the address back to the user
2596 * space one. This would work if the status/length fields written back
2597 * by the async URB completion lines up perfectly in the 32-bit type with
2598 * the 64-bit kernel type. Unfortunately, it does not because the iso
2599 * frame descriptors, at the end of the struct, can be written back.
2600 *
2601 * I think we'll just need to simply duplicate the devio URB engine here.
