From 9fa001cf3bb0598aad09d15b2896f7db9ef87637 Mon Sep 17 00:00:00 2001 From: Roman Gushchin Date: Mon, 1 Jul 2024 18:59:31 +0000 Subject: [PATCH] mm: memcg: drop obsolete cache line padding in struct mem_cgroup After the grouping of the cgroup v1-related fields and the corresponding reorganization of the struct mem_cgroup, the existing cache line padding doesn't make much sense anymore. Let's drop it for now and put back to new places, if necessary.
