struct {
u64 fielda
u32 field;
};
In this case: On 64 bit: the u64 is aligned to 8 and the u32
is aligned to 4. So
the structure is aligned to 8. A pad is inserted at the end of the
struct to bring it out. On 32 bit, the u64 is aligned to 4, so the
struct is aligned to

David is saying you will get a 12 byte struct and fieldb will be unaligned.
Since
12 is aligned to 4 no padding is added.
So I decided to experiment above example before implementing in
driver. However I find
Got it. You did mention about typedef in email chain, but I understood as
different way to achieve same.
I reviewed my code and found that most of the fields between driver-adapter
doesn't need attribute.
So far (a) removing packed and (b) BUILD_BUG_ON looks sufficient for current
