storing metadata on a dedicated device

2012-04-10 Thread Jan Killius 
Hello,
I just wanted to ask if storing metadata on a dedicated device is
implemented at the moment ?
It's listed under Project ideas and there is supposed to be a patch
but I can't find it anywhere.

Greetings
Jan Killius

AFAIK, not yet, but it is on plan :)

Yes, but not high in priority.

The old patch set was basically working (as far as I remember), but
there's no chance you can just happily apply it to the current btrfs
code without substantial rewrite.
