    net: Unmap fragment page once iterator is done · aeb193ea
    Wedson Almeida Filho authored
    Callers of skb_seq_read() are currently forced to call skb_abort_seq_read()
    even when consuming all the data because the last call to skb_seq_read (the
    one that returns 0 to indicate the end) fails to unmap the last fragment page.
    
    With this patch callers will be allowed to traverse the SKB data by calling
    skb_prepare_seq_read() once and repeatedly calling skb_seq_read() as originally
    intended (and documented in the original commit 677e90ed), that is, only call
    skb_abort_seq_read() if the sequential read is actually aborted.
