Note that we still have a potential underindication on _PAGE_REFERENCED in the unlikely event that the page was changed but not referenced _and_ someone references the page in the race window. That's not considered to be a problem. Signed-off-by: Carsten Otte Signed-off-by: Martin Schwidefsky --- Reading git-diff-tree failed
