Filling gaps and holes in hardwood floor

I have just sanded hardwood floor in my house (I think it's oak hardwood floor), and noticed several spots with "holes" (not all the way through--more like "small pothole in a road" kind of thing) and noticeable gaps in some areas (perhaps about 1/8 inch wide). I learned that these need to be filled (e.g. with wood filler). I am planning to use Tung oil with natural solvent to seal the wood (instead of using polyurethane). Is it a problem if I do the filling after the Tung oil? My reasoning is that the filler is not natural wood anyway, and won't be affected/covered by the oil, so I can do something else to match the color of the filled area.

How big are these holes? Filler often doesn't stain nicely and can look bad after finishing. Filling cracks usually looks ok because it's a straight line between 2 boards.
