This is the folio equivalent of mem_cgroup_page_lruvec().

I'm just going through and removing the wrappers.

Why is this function called this?  There's an odd mix of

lock_page_memcg()
page_memcg()
count_memcg_page_event()
split_page_memcg()

vs

mem_cgroup_charge()
mem_cgroup_swapin_charge_page()
mem_cgroup_lruvec()
mem_cgroup_from_task()

I'd really like to call this function folio_lruvec().  It happens to
behave differently if the folio is part of a memcg, but conceptually,
lruvecs aren't particularly tied to memcgs.


... are there any other functions you'd like to rename while I'm
changing pages to folios?
