From: Serge E. Hallyn <[email protected]> If CONFIG_IPC_NS=n, then checkpoint a sysvipcns of 0. If we end up restarted on a CONFIG_SYSVIPC=y host, we'll just end up using the parent sysvipcns, which is fine as we won't be trying to restore any sysvipc objects.
(The existing code worked fine with CONFIG_IPC_NS=n, but not with CONFIG_SYSVIPC=n and CONFIG_POSIX_MQUEUE=n. But we trigger on CONFIG_IPC_NS since even if CONFIG_SYSVIPC=y but CONFIG_IPC_NS=n, checkpointing 0 is right). Signed-off-by: Serge E.
