Message-ID: <20240906073646.2930809-10-linyunsheng@huawei.com> Date: Fri, 6 Sep 2024 15:36:41 +0800 From: Yunsheng Lin <linyunsheng@...wei.com> To: <davem@...emloft.net>, <kuba@...nel.org>, <pabeni@...hat.com> CC: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, Yunsheng Lin <linyunsheng@...wei.com>, Alexander Duyck <alexander.duyck@...il.com>, Eric Dumazet <edumazet@...gle.com>, David Ahern <dsahern@...nel.org> Subject: [PATCH net-next v18 09/14] net: rename skb_copy_to_page_nocache() helper Rename skb_copy_to_page_nocache() to skb_copy_to_va_nocache() to avoid calling virt_to_page() as we are about to pass virtual address directly.
