If the oom killer kills a thing like init by mistake or init has a memleak you'll notice both problems regardless of having a magic for init in a _very_ slow path so I don't buy your point. . For corretness init must not be killed ever, period. So you have two choices: o math proof that the current algorithm without the magic can't end killing init (and I should be able to proof the other way around instead) o have a magic check for init So the magic is _strictly_ necessary at the moment.
