You have talked about blkid, I thought you want to add SUBVOL= to
libblkid.
For what purpose do you need it in lsblk? When the same device is
mounded on more places?
Anyway, in libmount we can extend mnt_fs_* API and add some additional
functions -- for example add mnt_fs_get_default_root().
I definitely don't want btrfs specific functions. The API should be
generic.
