How to create an instance of MapperFlush?

[toku-sa-n]

I was trying to implement Mapper for my process struct and noticed that MapperFlush::new is a private method. Is there a way to create an instance of it?

From the MapperFlushAll docs:

This type is returned from a function that made the change to ensure that the TLB flush is not forgotten.

Basically, you are not supposed to be able to create this type. It is returned from functions like: Mapper::set_flags_p4_entry forcing the user to explicitly do something with the MapperFlush object.

See this example for how the type is used.

Then, is it not supposed to implement Mapper manually? Implementing it needs to create an instance of MapperFlush and MapperFlushAll.

@toku-sa-n whoops my bad, I misread your initial comment. Yes I believe external implementations of mapper should be supported, so we do need to add the constructors for this to be possible.

Good catch.
