Account memory consumed by secretmem to memcg. The accounting is updated
when the memory is actually allocated and freed.

I think this is wrong.  It fails to account subsequent allocators from
the same PMD.  If you want to track like this, you need separate pools
per memcg.

Are these secretmem pools shared between different jobs/memcgs?
