* Fixed buster compile-time issue * Host services inherit from ModePageDevice * Call base class * Visibility update * Updated includes * Updated dispatcher * Added TODOs * Logging update * Code cleanup * Use namespace instead of class for ScsiDefs * Renaming * Cleanup * Use dispatcher template in order to remove duplicate code * Updated all dispatchers * Clean up commands * Removed duplicate code * Removed duplicate code * Updated template definition * Fixed typo * Fixed warning * Code cleanup * Device list must be static * Cleanup * Logging update * Added comments * Cleanup * Base class update * SCSIBR is not a subclass of Disk anymore, but of PrimaryDevice * Updated includes * Fixed compile-time issue on the Pi * Header file cleanup * Interface cleanup * Removed wrong override * include file cleanup * Removed obsolete usage of streams * Removed more stream usages * Stream usage cleanup * Include cleanup * Renaming * Include cleanup * Interface update
