Hi All,
I have some questions regarding below two methods in
drivers/usr/core/urb.c source code.
Methods:
void usb_kill_urb(struct urb *urb)
void usb_poison_urb(struct urb *urb)
In both functions we have used `wait_event` method but haven't checked
for the condition `atomic_read(&urb->use_count) == 0` before going to sleep.
Should we add the check before putting the calling process to sleep or
avoiding check is intended (please explain if yes).
Regards
Kumar Gaurav
