From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jakub Sitnicki Subject: [PATCH net-next 1/5] ipv6: Fold rt6_info_hash_nhsfn() into its only caller Date: Mon, 24 Oct 2016 11:28:48 +0200 Message-ID: <1477301332-23954-2-git-send-email-jkbs@redhat.com> References: <1477301332-23954-1-git-send-email-jkbs@redhat.com> Cc: linux-kernel@vger.kernel.org, "David S. Miller" , Alexey Kuznetsov , James Morris , Hideaki YOSHIFUJI , Patrick McHardy To: netdev@vger.kernel.org Return-path: In-Reply-To: <1477301332-23954-1-git-send-email-jkbs@redhat.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Commit 644d0e656958 ("ipv6 Use get_hash_from_flowi6 for rt6 hash") has turned rt6_info_hash_nhsfn() into a one-liner, so it no longer makes sense to keep it around. Also the accompanying documentation comment has become outdated, so just remove it altogether.
