    sys/sys              msg.h sem.h shm.h 
  Log:
  First of several commits to allow kernel System V IPC data structures
  to be modified and extended without breaking the user space ABI:
  
  Define _kernel wrapper data structures for the user-exposed data
  structures that current server as the internal data structures for
  the implementation:
  
  - struct msqid_kernel wraps struct msqid_ds.
  - struct semid_kernel wraps truct semid_ds.
  - struct shmid_kernel wraps struct shmid_ds.
  - Don't expose extern definition 'shmsegs' outside of sysv_shm.c.
