From 04919bed948dc22a0032a9da867b7dcb8aece4ca Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Wed, 15 Jun 2022 09:20:11 -0700 Subject: tcp: Introduce tcp_read_skb() This patch inroduces tcp_read_skb() based on tcp_read_sock(), a preparation for the next patch which actually introduces a new sock ops. TCP is special here, because it has tcp_read_sock() which is mainly used by splice(). tcp_read_sock() supports partial read and arbitrary offset, neither of them is needed for sockmap.
