I just pulled up the carpet, pad, and tack-less strips from a bedroom. Underneath is an oak floor in reasonable condition. The only problem I have is that where the tack-less strips were pulled out, there are small holes in the floor, every 4-6". Many of the holes have turned black (from rusty tacks?).

So how should I handle these holes, some are as big as 1/8"? Filling the holes with wood putty, then sand and refinish the whole floor seems like a lot of work and/or expense. Any other suggestions?
