Thanks. But usually such padding things are added as "u8" (1 byte) variables. This makes it easier to calculate the offsets. In this case:
+ u8 padding2[0x30];
which I would prefer.
Thanks, Stefan

I don't mind either way, I can amend the patch (if you don't mind), so let's hear Dinh's final word.

If we use u8 in the place we should change the padding1 in the same struct as well.

In that case, we keep it as-is . Subsequent patch is welcome if anyone cares.
