Because then THP stops being Transparent.
But given the difficulties redis and php and presumably other programs appear to have, the whole idea of transparency is a bug not a feature, is it not?
Not if every system that doesn't run redis is doing better because of it ?
There are a *lot* of systems that run PHP. And I'm sure there are lots of other applications that use small memory blocks. Why should they be penalised?
Surely it's better to have a design where programs that want to use a new feature ask for it and programs that don't aren't forced to use it?
huge pages is not really a user/application level feature.
