I don't see any problems with changing struct kstat.  There would be
reservations against changing inode.i_ino though.

So filesystems that have 64bit inodes will need a specialized
getattr() method instead of generic_fillattr().

And they are already free to do so.  And no, struct kstat doesn't need
to be changed - it has u64 ino already.

If I return 64-bit values as ino_t, 32-bit programs will get EOVERFLOW on stat attempt (even if they are not going to use st_ino in any way) --- I know that POSIX specifies it, but the question is if it is useful.

What is the correct solution? Mount option that can differentiate between 32-bit colliding inode numbers and 64-bit non-colliding inode numbers? Or is there any better idea.

Given the fact that glibc compiles anything by default with 32-bit ino_t, I wonder if returning 64-bit inode number is possible at all.
