Hi, Andrew,
I mostly agree with your decision. I am a little concerned however
that as we develop and add more features (a.k.a better statistics/
forced reclaim), which are very important; the code base gets larger,
the review takes longer :)
I was hopeful of getting the bare minimal infrastructure for memory
control in mainline, so that review is easy and additional changes
can be well reviewed as well.
Here are the pros and cons of merging the memory controller
Pros
1. Smaller size, easy to review and merge
2. Incremental development, makes it easier to maintain the
code
Cons
1. Needs more review like you said
2. Although the UI is stable, it's a good chance to review
it once more before merging the code into mainline
Having said that, I'll continue testing the patches and make the
solution more complete and usable.
