Hi Yongqiang,

I'd like to hear back from Mingming and Allison about whether these
patches conflict with their punch patches, since my understanding was
they were planning on doing very similar things (and at least would be
working in the very similar parts of the code).

I agree that the extents code here could definitely use this cleanup,
and I'm really glad that you worked on this; thank you!  I just want
to make sure work you are doing is coordinated with the work that
Allison and Mingming are working on.
