Functions here is started with "Be-verb + Arc", how about following it?
E.g. IsArcCompatibleFileSystemUsedForProfile()?

Done.

 // Disallows ARC for all profiles for testing.

 // secondary profile). On the other hand, some test infra does not support
 // such situations (e.g. API test). This is for workaround to emulate the
