From aeb193ea6cef28e33589de05ef932424f8e19bde Mon Sep 17 00:00:00 2001 From: Wedson Almeida Filho Date: Sun, 23 Jun 2013 23:33:48 -0700 Subject: net: Unmap fragment page once iterator is done 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 677e90eda), that is, only call skb_abort_seq_read() if the sequential read is actually aborted.
