This is like container_of() but it has an assert to ensure that it's
using the first struct member.


I just remembered that Greg wanted this based on container_of_const().

Yes, that would be best.

Okay, I'll change that.

Really container_of_const() should be renamed to container_of() and
container_of() should be renamed to container_of_helper() and we
would add a #define container_of_const container_of for the transition.

I agree, but I wonder if it's safe to just do that already and how many
build warnings would happen. Last I checked it was a lot.

thanks,
