// missingdefs.h
//
// Defines types that are not available in vmlinux.h
//
// Unfortunately, today, when including vmlinux.h there is no way to 
// prevent redefinitions and hence we need to remove all headers that
// cause redefitions. By doing so however, we also miss the defitions
// in those headers that vmlinux.h does not define. This is a known 
// problem and the current solution is to define those types seperately. 
// This files contains all the defs that are missing. 
//
