It's currently inconvenient to retrieve MM_ANONPAGES value from status
and statm files and there is no way to separate MM_FILEPAGES and
MM_SHMEMPAGES. Add RssAnon, RssFile and RssShm lines in /proc/<pid>/status
to solve these issues.

This changelog is also head-spinning.

Why is it talking about MM_ANONPAGES and MM_FILEPAGES in the context of
procfs files?  Those terms are kernel-internal stuff and are
meaningless to end users.

So can we please start over with the changelogs?

- What is wrong with the current user interface?

- What changes are we proposing making?

- What new fields are added to the UI?  What is their meaning to users?

- Are any existing UI fields altered?  If so how and why and what
  impact will that have?

Extra points will be awarded for example procfs output.

This is the important stuff!  Once this is all clearly described,
understood and reviewed, then we can get into the
kernel-internal-microdetails like MM_ANONPAGES.


(And "What is wrong with the current user interface?" is important. 
What value does this patchset provide to end users?  Why does anyone
even want these changes?)
