    Description

      When rename() has a target directory with different project ID from the source directory, the kernel currently returns -EXDEV, which forces userspace to perform a full data copy of the file. This is slow when the files are large, and does not provide any security benefit for the user or admin in the end.

      It would be better to change the project ID to that of the target directory, and assign the quota for the file to the new project ID, the same as is done with chown() and chgrp() for UID and GID quotas.
