    [INET]: Use pskb_trim_unique when trimming paged unique skbs · e9fa4f7b
    Herbert Xu authored
    The IPv4/IPv6 datagram output path was using skb_trim to trim paged
    packets because they know that the packet has not been cloned yet
    (since the packet hasn't been given to anything else in the system).
    
    This broke because skb_trim no longer allows paged packets to be
    trimmed.  Paged packets must be given to one of the pskb_trim functions
    instead.
    
    This patch adds a new pskb_trim_unique function to cover the IPv4/IPv6
    datagram output path scenario and replaces the corresponding skb_trim
    calls with it.
