As Chao's said, we keep on fetching the latest Greg's staging tree and develop
, preview, and test new erofs features and bugfix based on it.

For the cleanup patches, it could be better directly based on Greg's upstream
staging tree. We will then rebase our developping code on your work. :)

Yes, we are sorry about that. could you please send v4 patch which follows Greg's
and Chao's suggestions?
