Hello,
In drivers/usb/core/hcd.c: usb_hcd_flush_endpoint() uses
list_for_each_entry() to unlink URBs pending on
endpoint. At the same time unlink1() calls usb_rh_urb_dequeue()
where URB is removed from its endpoint queue:
void usb_hcd_unlink_urb_from_ep(struct usb_hcd *hcd, struct urb *urb)
{
/* clear all state linking urb to this dev (and hcd) */
spin_lock(&hcd_urb_list_lock);
list_del_init(&urb->urb_list);
spin_unlock(&hcd_urb_list_lock);
}
Shall we use safe version of list_for_each_entry() for cancelling URBs?
Thanks.
