Hi Tom,

I also do not see a pragma pack, usually this is set of 1 so the compiler does not shuffle elements, increase size etc.
This data structure is shared with other tools. And the structure is well defined with reasonable alignment. It is compatible with all compilers we have tested. So pragma pack is not necessary.
You can not have possibly tested all the configurations since the kernel supports many arches and compilers.
If the tested existing alignment is ok, pragma pack should be a noop on your tested configurations.
And help cover the untested configurations.
Got it. I will add pragma pack(1).
Please do not use pragma pack(), add __packed to the structs in
question.
Ok, I will use __packed.
Thanks,
