The kernel abbreviates these as: capprm & capinh in the proc file system. I'm 
thinking shorter names would save some disk space.

No. Its my understanding that apps could have something inheritable by 
children and we'd want to know exactly what that was.

Yes.

That would be strange to have a field that is not used.

I'll leave code review to others. Thanks for working on this patch!
