Yes, PRIu64 is "lu", uint64_t is long unsigned int, but __u64 isn't.
So we can print uint64_t by using "PRIu64", but we can't do this for 
__u64 when we want to print any data defined as "__le64" in ocfs2_fs.h.

It seems that my commit log is somewhat wrong. Sorry for that.
I will resend the patch.
