Thanks for reminding me of extent(9). I haven't used it before. I
probably should be using that, but I'm not sure how to. I don't see
a way to allocate "the first aligned, N-byte segment" from an extent.
With extent(9), I need to specify where that region is. Would it make
sense to specify an extent_find_region() and/or extent_find_region1()
to do a find the first region that matches the specified size & alignment?
It could then alloc and/or just return the base of the region.
Thoughts?
