Thank you for looking at this change. What you described was in my
previous iterations of this project.

See for example here: https://lkml.org/lkml/2017/5/5/369

I was asked to remove that flag, and only zero memory in place when
needed. Overall the current approach is better everywhere else in the
kernel, but it adds a little extra code to kasan initialization.

Perhaps you could #define the function prototype(s?) so that the flags
are not passed unless it is a kasan build?

Hi David,

Thank you for suggestion. I think a kasan specific vmemmap (what I described in the previous e-mail) would be a better solution over having different prototypes with different builds. It would be cleaner to have all kasan specific code in one place.
