Description

A very small marking bitmap (2 bits) is sufficient for large object page since just one object in it. This is a proposal patch to shrink LO page's marking bitmap to save memory footprint, approximately 32K marking bitmap saved for each LO page. Patch has passed tools/presubmit.py and tools/test.py. Please kindly review and comment as appropriate.
