From c51da3f7a161c6822232be832abdffe47eb55b4c Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 20 Jun 2025 13:30:01 +0000 Subject: net: remove sock_i_uid() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Difference between sock_i_uid() and sk_uid() is that after sock_orphan(), sock_i_uid() returns GLOBAL_ROOT_UID while sk_uid() returns the last cached sk->sk_uid value. None of sock_i_uid() callers care about this. Use sk_uid() which is much faster and inlined. Note that diag/dump users are calling sock_i_ino() and can not see the full benefit yet.
