  HAMMER 51/Many: Filesystem full casework, nohistory flag.
  
  * Track the amount of unsynced information and return ENOSPC if the
    filesystem would become full.  The idea here is to detect that the
    filesystem is full and yet still give the flusher enough runway to
    flush cached dirty data and inodes.
  
  * Implement the NOHISTORY flag.  Implement inheritance of NOHISTORY and
    NODUMP.
  
    The NOHISTORY flag tells HAMMER not to retain historical information on
    a filesystem object.  If set on a directory any objects created in that
    directory will also inherit the flag.  For example, it could be set
    on /usr/obj.
