Description

Certain of the implementations of FsVolumeSpi say for eg:- FsVolumeImpl can implement equals and hashcode. This is to avoid object identity check during disk check scheduling in ThrottledAsyncChecker and instead use other means of checking whether a diskcheck is already in progress or not for FsVolumeImpl object.
