There is a build error and also checkpatch complains about style issues.

You need to use PRIu64 and friends to get this working:

printf("Estimated offset : %"PRIu64"\n", le64_to_cpu(stats->est_offset))

@igaw - I have fixed the issue. Please check

[igaw]

You need to use the same memcpy trick as above, this likely to work on platforms which enforce data alignment.

The rest looks good.

I've just updated the cross build containers, thus there are a bunch of new bugs. I'm fixing them up right now.

Thanks!
