Well that was useful.  Andrey, please slurp Dmitry's info into the 0/n
changelog?

Also, some quantitative info about the kmemleak overhead would be
useful.

In this discussion you've mentioned a few planned kasan enhancements. 
Please also list those and attempt to describe the amount of effort and
complexity levels.  Partly so other can understand the plans and partly
so we can see what we're semi-committing ourselves to if we merge this
stuff.
