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: statfs.go
    path of file: ./repos/delve/vendor/github.com/cilium/ebpf/internal
    
    the code of the file until where you have to start completion: package internal

import (
	"unsafe"

	"github.com/cilium/ebpf/internal/unix"
)

func FSType(path string) (int64, error) {
	var statfs unix.Statfs_t
	if err := unix.Statfs(path, &statfs); err != nil {
		return 0, err
	}

	fsType := int64(statfs.Type)
	if unsafe.Sizeof(statfs.Type
    
func FSType(path string) (int64, error) {
	var statfs unix.Statfs_t
	if err := unix.Statfs(path, &statfs); err != nil {
		return 0, err
	}

	fsType := int64(statfs.Type)
	if unsafe.Sizeof(statfs.Type) == 4 {
		// We're on a 32 bit arch, where statfs.Type is int32. bpfFSType is a
		// negative number when interpreted as int32 so we need to cast via
		// uint32 to avoid sign extension.
		fsType = int64(uint32(statfs.Type))
	}
	return fsType, nil
}
