From 33d60fbd21fa6f71a88571209e301ec6de59f81b Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Wed, 8 Dec 2021 15:21:58 +0900 Subject: sock: Use sock_owned_by_user_nocheck() instead of sk_lock.owned. This patch moves sock_release_ownership() down in include/net/sock.h and replaces some sk_lock.owned tests with sock_owned_by_user_nocheck().
