The may_swap scan control flag can be naturally merged into the
swappiness parameter: swap only if swappiness is non-zero.
Sorry, NAK.
AFAIK, swappiness==0 is very widely used in MySQL users community.
They expect this parameter mean "very prefer to discard file cache
rather than swap, but not completely disable swap".
We shouldn't ignore the real world use case. even if it is a bit strange.
