The indentation is still not fixed, AFAICS. How do you do the backports? Picking up and applying the full changsets, or making the patch by hand?

In the [master](https://github.com/openjdk/jdk) repository, there are other modifications to [unsafe.cpp](https://github.com/openjdk/jdk/commits/master/src/hotspot/share/prims/unsafe.cpp ).  Other modifications do not belong to this bug. What should I do next? This is my first time submitting code, and there are many areas that I am currently studying. Thank you for your guidance.
