Yes, but how do you call getattr() without a path?

You don't because inode numbers are irrelevant without the path.

They are for kernel messages and audit logs.  Please take a look at the
use cases with the other patches.

It still is useless.  E.g. btrfs has duplicate inode numbers due to
subvolumes.

If you want a better pretty but not useful value just work on making
i_ino 64-bits wide, which is long overdue.
