    Description

      For ZGC we added the ability to skip clearing a bitmap when it was created. With the ZUncomit patch, we want to be able to resize the bitmaps, without clearing them, when pages are split.

      Suggestion is that we add a 'clear' parameter to initialize, resize, and reinitialize, just like we have for the CHeapBitMap constructor.
