Thanks. It's interesting that I followed sashiko previous suggestion,
cause it's a trivial part, and now sashiko is suggesting to change it
back to what I was doing :)

Nothing critical and I just saw a false positive, but anyway, I'll
forward the review to corresponding patch, I do prefer to change it
back to the previous design, maybe do some other slight improvement
too. Let me send an update in a few days after double checking the
swappiness issue reported by Barry.
