How to get the inode number with ->getattr and only a struct inode?

You get a struct kstat and extract it from that.

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.
