The latest btrfs-unstable seems not have BTRFS_IOC_SNAP_LISTING, neither btrfs_ioctl_default_subvol. With what revision of btrfs do you work? Of course I could apply it manually but I''m interested in the snap listing, too :) * I did not succeed in finding the patch ''-i''. If you would happen to know where I can find it? I was looking on linux-btrfs mailing list and asked the allknowing Google.
