This function is enough for releasing resources, allocated for network namespace context, in case of sharing service between them. IOW, each service "user" (LockD, NFSd, etc), which wants to share service between network namespaces, have to release related resources by the function, introduced in this patch, instead of performing service shutdown (of course in case the service is shared already to the moment of release).
