I am fine with "page hinting". I have already gone through and started the
rename. The problem with "page recycling" is that is actually pretty
similar to the name we had in the networking space for how the NICs will
recycle the Rx buffers.

For now I am going through and replacing instances of Aerated with Hinted,
and aeration with page_hinting. I should have a new patch set ready in a
couple days assuming no unforeseen issues.

Thanks.
