The change can only be made for methods that return an error, so Fd and Name are not
candidates.
The following program prints:
Chdir panicked
Chmod panicked
Chown panicked
Close panicked
Readdir panicked
Readdirnames panicked
Seek panicked
Stat panicked
Truncate panicked
package main
import (
    "fmt"
    "os"
)
func test(name string, f func()){
    defer func() {
        if recover() != nil {
            fmt.Println(name, "panicked")
        }
    }()
    f()
}
func main() {
    p := make([]byte, 10)
    test("Chdir", func(){(*os.File)(nil).Chdir()})
    test("Chmod", func(){(*os.File)(nil).Chmod(0)})
    test("Chown", func(){(*os.File)(nil).Chown(0, 0)})
    test("Close", func(){(*os.File)(nil).Close()})
    test("Read", func(){(*os.File)(nil).Read(p)})
    test("ReadAt", func(){(*os.File)(nil).ReadAt(p, 0)})
    test("Readdir", func(){(*os.File)(nil).Readdir(0)})
    test("Readdirnames", func(){(*os.File)(nil).Readdirnames(0)})
    test("Seek", func(){(*os.File)(nil).Seek(0, 0)})
    test("Stat", func(){(*os.File)(nil).Stat()})
    test("Sync", func(){(*os.File)(nil).Sync()})
    test("Truncate", func(){(*os.File)(nil).Truncate(0)})
    test("Write", func(){(*os.File)(nil).Write(p)})
    test("WriteAt", func(){(*os.File)(nil).WriteAt(p, 0)})
