Description
Traditionally, the cost prediction for scanning a card from the log buffers and the remembered set has been separate. In JDK-8200545 we merged the closures for both tasks; since JDK-8213108 there is no difference in the scanning a card from the remembered sets and the log buffers, there is a single task for it. There is no reason to have different scan cost predictions for both. Unifying this should also simplify the code and improve the accuracy of the predictions as we do not artificially split the task into two with this change.
