'btrfs fi show -d': Those were kind of anticipated ! http://www.spinics.net/lists/linux-btrfs/msg31445.html end users: pls just ignore -d output. Instead use with no option, which then uses the kernel data for the mounted FS and userland data for the unmounted. 'btrfs dev ready': - cannot be fixed without breaking the API rules. May be we would obsolete this cli to a sysfs interface or something else.
