    sys/sys              msg.h 
  Log:
  Second of several commits to allow kernel System V IPC data structures
  to be modified and extended without breaking the user space ABI:
  
  Use _kernel variants on _ds structures for System V sempahores, message
  queues, and shared memory.  When interfacing with userspace, export
  only the _ds subsets of the _kernel data structures.  A lot of search
  and replace.
  
  Define the message structure in the _KERNEL portion of msg.h so that it
  can be used by other kernel consumers, but not exposed to user space.
