This updated tree now includes a fix for virtio-net regression that was present in 5.14: commit 732b74d647048668f0f8dc0c848f0746c69e2e2f Author: Xuan Zhuo <xuanzhuo@linux.alibaba.com> Date: Sat Oct 9 05:17:53 2021 -0400 virtio-net: fix for skb_over_panic inside big mode commit 126285651b7f ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net") accidentally reverted the effect of commit 1a8024239da ("virtio-net: fix for skb_over_panic inside big mode") on drivers/net/virtio_net.c As a result, users of crosvm (which is using large packet mode) are experiencing crashes with 5.14-rc1 and above that do not occur with 5.13.
