My situation is this:
- interrupts are off
- one xenolinux network device is active
- there are buffered rx requests in the rx_ring
- I need to reset this ring in a minute
- I wish to free all the out-of-band pages allocated in my guest OS, so
they are not leaked when I reset the ring
I am trying this:
NET_RING_IDX i = np->net_idx->rx_resp_prod;
while (i != np->net_idx->rx_req_prod)
{
 unsigned short id =
np->net_ring->rx_ring[MASK_NET_RX_IDX(i++)].req.id;
 struct sk_buff* skb = np->rx_skbs[id];
 dev_kfree_skb_any(skb);
}
-- which crashes on dev_kfree_skb_any().
Can anyone tell my why I cannot free these skbs?
Thanks,
Jacob
