How to determine fragment restored from backstack

I think that most simple way is do this for example in onViewCreated() method:

if (savedInstanceState == null && !mAlreadyLoaded) {
    mAlreadyLoaded = true;

    // Do this code only first time, not after rotation or reuse fragment from backstack
}

Because when android put fragment on backstack, it only destroy its view, but don’t kill instance itself, so mAlreadyLoaded will be still true when fragment will be restored from backstack.
