Frankly, I'm modest, what about to have both interfaces in kernel --
fsinfo() as well mountfs? It's nothing unusual for example for block
devices to have attribute accessible by /sys as well as by ioctl().
I can imagine that for complex task or performance sensitive tasks
it's better to use fsinfo(), but in another simple use-cases (for
example to convert mountpoint to device name in shell) is better to
read /proc/.../<atrtr>.
