+ * This is problematic since there are many call sites from which the
+ * async entries can be destroyed (and thus when we'd need to free up
+ * this kernel memory). One of which is the close() op of usbdevicefs.
+ * To handle that we'd need to make our own file_operations struct which

+ *
+ * But how to keep track of these kernel buffers? We'd need to either
+ * keep track of them in some table _or_ know about usbdevicefs internals
+ * (ie. the exact layout of it's file private, which is actually defined
+ * in linux/usbdevice_fs.h, the layout of the async queues are private to
+ * devio.c)
+ *
+ * There is one possible other solution I considered, also involving knowledge
+ * of usbdevicefs internals:
+ *
+ * After an URB is submitted, we "fix up" the address back to the user
+ * space one. This would work if the status/length fields written back
+ * by the async URB completion lines up perfectly in the 32-bit type with
+ * the 64-bit kernel type. Unfortunately, it does not because the iso
+ * frame descriptors, at the end of the struct, can be written back.
+ *
+ * I think we'll just need to simply duplicate the devio URB engine here.
