VFS CHANGES: - dmap table no longer statically initialized in VFS - Dropped FSSIGNON svrctl call no longer used by INET INET CHANGES: - INET announces its presence to VFS just like any other driver RS CHANGES: - The boot image dev table contains all the data to initialize VFS' dmap table - RS interface supports asynchronous up and update operations now - RS interface extended to support driver style and flags
