Subject: Re: [RFC PATCH v2 1/2] mm: tuning hardcoded reserved memory

The 3% reserve was added to the original code *because* users kept hitting
problems where they couldn't recover. 

I suspect the tunable should nowdays be something related to min(3%,
someconstant), at the time we did the 3% I think 1GB was an "enterprise
system" ;)
