[PATCH] mm: vmscan: provide a change to the development-process group

I think this change is needed for safety, whatever that might mean to you.

I am unqualified to really make a change here, as I have no clue what this
code does, nor what my change does, but sure, the testing and verification
reference process can now point out the required next steps in the
reference process to test this code and code change.

Good luck :)

I would like to submit such a patch, what do I need to do according to
the expected testing and verification recommendations for safety-related
systems?

Please help me. What do I need to compile, what test do I need to run,
which verification tool do I need to employ for this change?

Or even more basic: where would I even find that information?
