I'm not an expert in this code but IMO the pointer manipulation of
page->mem_cgroup could be thought of as local to the code in mm/memcontrol.c.
As such the detail of the member of the page struct that the code depends on is
a valuable part of the comment. Having to look at page_memcg() to find out
this information is kind of annoying.

There are "page and memcg binding" and "page's memcg" used in similar cases,
I think it's more obvious than "page_memcg(page) being stable".
Maybe it helps to address Ira's comment.
Anyway, please feel free to add:
