I dropped 059b7dbd20a6 ("vsock/virtio: fix potential unbounded skb queue") from the 6.6 queue, together with its two prerequisites that were queued only for it: - 0df7cd3c13e4 ("vsock/virtio/vhost: read data from non-linear skb") - 45ca7e9f0730 ("vsock/virtio: fix `rx_bytes` accounting for stream sockets") It is dropped from 6.1 as well. If it comes back to 6.6, it will be with the complete set of fixes. -- Thanks, Sasha
