the warning probably started to show up after one of my cleanup patches,
removing unused functions (f2a97a9dbd86eb1ef956bdf20e05c507b32beb96).
The sysfs interface is not being used right now, but there's a unmerged
patchset which adds the interesting bits like info about available btrfs
filesystems and devices. I don't know what are the intentions regarding
sysfs.
