To be very blunt, not actually testing changes of this nature isn't acceptable.
The HugeTLB dependency of dirty_log_page_splitting_test makes it annoying to run,
as does the root user dependency of nx_huge_pages_test.sh, but I wouldn't say
that running them is hard.
It's a-ok to not fully test code when you don't have the necessary hardware,
configuration, etc., but generally speaking the expectation is that you test the
code you post.

Converting vm_get_stats() to a macro, or rather, changing its parameter to do
token pasting, absolutely must update all users at the same time. With only the
previous patch applied, the affected tests fail because they try to get stats
for the string "\"<stat>\"".
