From 0d2e27b858503472f8ed66910498205824b02f8a Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Wed, 14 Jun 2023 16:01:05 -0700 Subject: [PATCH] ipv6: exthdrs: Replace pskb_pull() with skb_pull() in ipv6_srh_rcv(). ipv6_rthdr_rcv() pulls these data - Segment Routing Header : 8 - Hdr Ext Len : skb_transport_header(skb)[1] << 3 needed by ipv6_srh_rcv(), so pskb_pull() in ipv6_srh_rcv() never fails and can be replaced with skb_pull().
