[RFC PATCH v1 3/3] virtio/vsock: remove all data from sk_buff

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In case of SOCK_SEQPACKET all sk_buffs are used once - after read some
data from it, it will be removed, so user will never read rest of the
data. Thus we need to update credit parameters of the socket like whole
sk_buff is read - so call 'skb_pull()' for the whole buffer.
