Having some aggregate number in /proc/meminfo would probably be fine.

And yes, we probably should avoid giving page-level granularity in
/proc/meminfo too. Do it in megabytes instead. None of the information
there is really relevant at a page level, everybody just wants rough
aggregates.

We have this in /proc/meminfo:

Slab:              20012 kB

Or did you mean something even more specific?

Oh, sorry, I completely misread what you wrote above. Sure, we can
round the numbers into megabytes without breaking the ABI.
