The problem with this is that then we have to modify a lot of lines from, let's say, instance->used, instance->size, etc... to instance->hdr.used, instance->hdr.size, and so on...Great, let's do that and get it right please.
Deal!
This code churn is avoided if we use the struct_group() helper.It's not "churn" if it is "fix the code to be correct" :)
As long as those warnings are fixed and we harden the kernel, I'm really okay with whatever maintainers prefer. :) Thanks! -Gustavo
