- Innochecksum misinterprets the freed pages as active one. This leads the user to think there are too many valid pages exist. - To avoid this confusion, innochecksum introduced one more option --skip-freed-pages and -r to avoid the freed pages while dumping or printing the summary of the tablespace. - Innochecksum can safely assume the page is freed if the respective extent doesn't belong to a segment and marked as freed in XDES_BITMAP in extent descriptor page. - Innochecksum shouldn't assume that zero-filled page as extent descriptor page.
