Hi, all In usb.c (kernel 2.4.20, I have to work on this kernel version),
function usb_start_wait_urb() sets the process state to TASK_UNINTERRUPTIBLE and add the process to awd.wqh before calling usb_submit_urb(). What is this for? And What if scheduling happens during the usb_submit_urb() but before it calls urb->complete to wake the process? A TASK_UNINTERRUPTIBLE process wont have chance to run, right? Isnt this a deadlock? (please correct me if I am wrong).
