It looks like we're now dropping into direct reclaim as the first thing
in __alloc_pages before even trying to kick off kswapd. When the hell
did that start? Or is that only meant to trigger if we're already below
the low watermark level?

That's all the numa goop which Martin Hicks added.  It's all disabled if
z->reclaim_pages is zero (it is).  However we could be testing that flag a
bit earlier, I think.

And yeah, some de-spaghettification would be nice.  Certainly before adding
more logic.

Martin, should we take out the early zone reclaim logic?  It's all
unreachable at present anyway.

Yes, Please do.
