I'm seeing the splat below after this series. I'm still wrapping my head around this code, but it appears to be happening because the tun_struct passed into tun_queue_resize is uninitialized. Specifically, iteration over the disa...

[PATCH net-next V4 0/6] switch to use tx skb array in tun
Hi all: This series tries to switch to use skb array in tun. This is used to eliminate the spinlock contention between producer and consumer. The conversion was straightforward: just introdce a tx skb array and use it instead of sk_receive_queue. A minor issue is to keep the tx_queue_len behaviour, since tun used to use it for the length of sk_receive_queue. This is done through: - add the ability to resize multiple rings at once to avoid handling partial resize failure for mutiple...
