Hmm this does not seem right. What if:
i = 4294967296
j = 8589934592
then you would return 0 even though the two block numbers differs.
The problem here is that even though you compare __u64 you return
int.
Thanks!

Since you're possibly comparing 64bit numbers and return int this
would not work very well at all.

What is the difference between j and i here ? I've got the feeling
that both should be the same ?
Thanks!
