Modified files:
sys/kern sysv_msg.c sysv_sem.c sysv_shm.c
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.
