I can't waste my time in what you think the long term solution. Please
don't refuse/ignore my (or David's) patches without your counter
patches.

If you do not care about long term sanity of the code and if you do not
care about a larger picture then I am not interested in any patches from
you. MM code is far from trivial and no playground. This attitude of
yours is just dangerous.

Then, please explain how we guarantee that enough CPU resource is spent
between "exit_mmap() set MMF_OOM_SKIP" and "the OOM killer finds MMF_OOM_SKIP
was already set" so that last second allocation with high watermark can't fail
when 50% of available memory was already reclaimed.
