Subject: [PATCH net v4 2/4] virtio/vsock: remove redundant 'skb_pull()' call
Date: Tue, 14 Mar 2023 13:43:39 +0300 [thread overview]
Message-ID: <76f8ff7b-cf6f-8a6f-993c-416506686742@sberdevices.ru> (raw)
In-Reply-To: <34d65539-015e-23c8-cf5e-f34bd5795e52@sberdevices.ru>
Since we now no longer use 'skb->len' to update credit, there is no sense
to update skbuff state, because it is used only once after dequeue to
copy data and then will be released.
Fixes: 71dc9ec9ac7d ("virtio/vsock: replace virtio_vsock_pkt with sk_buff")
