You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: workarounds.go
    path of file: ./repos/ebpf/btf
    
    the code of the file until where you have to start completion: package btf

// datasecResolveWorkaround ensures that certain vars in a Datasec are added
// to a Spec before the Datasec. This avoids a bug in kernel BTF validation.
//
// See https://lore.kernel.org/bpf/20230302123440.1193507-1-lmb@isovalent.com/
func datasecResolveWorkaround(b *Builder, ds *Datasec) error {
	for _, vsi := range ds.Vars {
		v, ok := vsi.Type.(*Var)
		if !ok {
		
    
func datasecResolveWorkaround(b *Builder, ds *Datasec) error {
	for _, vsi := range ds.Vars {
		v, ok := vsi.Type.(*Var)
		if !ok {
			continue
		}

		switch v.Type.(type) {
		case *Typedef, *Volatile, *Const, *Restrict, *typeTag:
			// NB: We must never call Add on a Datasec, otherwise we risk
			// infinite recursion.
			_, err := b.Add(v.Type)
			if err != nil {
				return err

		}
	}

	return nil
