reference to frozen superblocks") in that it no longer returned
-EINVAL for superblocks that were not frozen.

Return -EINVAL when the filesystem is already unfrozen to avoid this
problem.

Jan, thank you for the detailed review of the patch set. I really appreciate it.

This week I am pretty busy with other stuff so I may not be able to address your

Regards,
Fernando
