Hmm, that bloats the kernel also for users who are not using cgroup2 and have CONFIG_MEMCG_KMEM disabled.
This is the situation before this patch text data bss dec hex filename 521342 97516 44312 663170 a1e82 mm/built-in.o.kmem 513349 96299 43960 653608 9f928 mm/built-in.o.nokmem
and after with CONFIG_MEMCG_KMEM=n
521028 96556 44312 661896 a1988 mm/built-in.o
we are basically back to CONFIG_MEMCG_KMEM=y. This sounds like a wastage to me. Do we really need this?
