[Devel] [PATCH hci-8.1 1/3] mm/memcontrol: drop the unused update_lru_sizes()

[Konstantin Khorenko <khorenko@virtuozzo.com>]

It has had no caller since commit 3c6e0c1ac1d6 ("mm/memcontrol: use
lruvec_del_folio() in memcg_numa_isolate_pages()"), and being static
__always_inline it never drew a warning.

https://virtuozzo.atlassian.net/browse/VSTOR-152197

Feature: mm: interface to migrate memory between NUMA nodes upon userspace request
