On the other hand, the sysctl names do not differ from namespace to namespace, and we already tuned the IPC sysctl code to handle the multy-namespace variables. I think, that registering tables for each namespace is just a waste of kernel memory and unneeded code. Thus, I just switch the IPC code to use the paths and keep current namespaces management code as is.
