Hi there, I've got a driver which maintains a pool of URBs, properly created via usb_alloc_urb(). Separately I have a cleanup function which destroys the pool by looping through the list and calling usb_kill_urb(), freeing the urb->transfer_buffer, and then calling usb_free_urb().
There are some edge cases where not all of the URBs may be in a submitted state when calling the cleanup function. Could this cause a problem? Is it legal to call usb_kill_urb() against a URB that hasn't had usb_submit_urb() called against it (or where the URB had been submitted but it has already completed and wasn't resubmitted)? I can certainly add additional logic to keep track of exactly which URBs in the pool are in a submitted state (so I call usb_kill_urb() against only submitted URBs but usb_free_urb against all URBs), but I would obviously prefer to avoid the headache and risk of additional bugs if it isn't necessary.
