From 43049b0db03823c2cd003ca7d3dddcd3924da8dc Mon Sep 17 00:00:00 2001 From: Kuniyuki Iwashima Date: Fri, 15 Aug 2025 20:16:15 +0000 Subject: net-memcg: Introduce mem_cgroup_sk_enabled(). The socket memcg feature is enabled by a static key and only works for non-root cgroup. We check both conditions in many places. Let's factorise it as a helper function.
