It works already if ./df t/ISO and t/Music/ are mount points. But it does not
work for nested directories. There can be a different quota set for them:
$ strace -e trace=statfs \
df -h /mnt/sorento /mnt/sorento/home /mnt/sorento/home/xdudka00
statfs("/mnt/sorento", ...) = 0
statfs("/mnt/sorento/home", ...) = 0
statfs("/mnt/sorento/home", ...) = 0
