fs_quota_statv is used by Q_XGETQSTATV for a given file system. It provides a centralized way to get meta information about the quota subsystem. eg. space taken up for user, group, and project quotas, number of dquots currently incore.

This version has proper versioning support with appropriate padding for future expansions, and ability to expand for future without creating any backward compatibility issues.

Q_XGETQSTATV uses the passed in value of the requested version via fs_quota_statv.qs_version to determine the return data layout of fs_quota_statv. The kernel will fill the data fields relevant to that version.

If kernel does not support user space caller specified version, EINVAL will be returned. User space caller can then reduce the version number and retry the same command.
