Re: [RFC PATCH v2 1/5] mm: mglru: avoid scanning empty generations in scan_folios()

[Lian Wang]

Hi Barry,

That makes sense. I agree that this rare corner case does not justify
the added complexity for now, so please feel free to leave it out of v3.

I'll test v3, with a particular focus on the generation-imbalance aging
behavior in 4/5, and report back with the results.

Thanks,
Lian
