Subject: mm: memcg: drop obsolete cache line padding in struct mem_cgroup
Date: Mon, 1 Jul 2024 18:59:31 +0000
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.
