With this patch and the latest net branch I no longer get crashes.

Did this ever get properly submitted to the networking tree to get into
5.13-final?

The patch has been submitted.

	[PATCH net] virtio-net: fix for skb_over_panic inside big mode

Submitted where?  Do you have a lore.kernel.org link somewhere?

https://lore.kernel.org/netdev/20210603170901.66504-1-xuanzhuo@linux.alibaba.com/ (local)

So this is commit 1a8024239dac ("virtio-net: fix for skb_over_panic
inside big mode") in Linus's tree, right?

But why is that referencing:
	Fixes: fb32856b16ad ("virtio-net: page_to_skb() use build_skb when there's sufficient tailroom")

when this problem was seen in stable kernels that had a different commit
backported to it?

Is there nothing needed to be done for the stable kernel trees?

confused,
