Therefore, here is a patch that does two things:
- default to "nocache"
- in case of failure with nocache, retry with "write-back"
This sort of change requires performance data in a variety of

that a more targeted change like making cache=none default for physical
devices would satisfy mostly everyone.
Is there any other thing than physical devices attached to the -drive
