Description

In Java Language Specification 9.4:

It is permitted, but discouraged as a matter of style, to redundantly specify the public and/or abstract modifier for a method declared in an interface.

FsDatasetSpi and FsVolumeSpi mark methods as public, which cause many warnings in IDEs and checkstyle.
