This was partially found by using a static code analysis program called cppcheck.

That assertion doesn't work in an unused function, but we still want
this check. Please move the BUILD_BUG_ON() to the beginning of
memcg_stat_show() instead.

to memcg_stat_show sounds like a good idea.

Hi
Ok, sure I'll fix that!
It will take a few days before I will have access to my workstation,
however, but the new patch on the way...

Remove function mem_cgroup_lru_names_not_uptodate() that is not used anywhere.
And move BUILD_BUG_ON() to the beginning of memcg_stat_show() instead.
This was partially found by using a static code analysis program called cppcheck.
