When no caching devices are connected, bcache-status shows nothing.
Although actually no caching happens, it's confusing.

Yep, works indeed.
Dispite the alarming description :-)
Suggestion for alternative text: "Detaches all caching devices and
closes them; if any data is present in the caching devices it will ..."

I noteced that one, but it looks kind of scary to me:
|"Detaches all backing devices and closes the cache devices; if dirty
data is present it will disable writeback caching and wait for it to
be flushed.|
Sounds like one of these:
- the /dev/cache* devices are gone; if so: that's definitely not what
I want.
- or at least the the baching devices are detached; that also sounds
bad. I don't want to detacht the backing devices at all, I want to
detacht the caching device.
The text is somewhat confusing to me. I'll give it a try, it's only a
VM.
