Thanks, Sorry, I misread. 'btrfs fi resize max ' should of course resize the entire FS. I think this popped up before, at least a couple times. I'll do it if nobody else wants to.

I'd keep the devid:max syntax for maxing out a single device and add a new fs:max or similar to resize all devices. ABI here is just a string, so I think it can be easily done.
