> There are several SLAB objects with a pointer to a namespace on them.
> These objects are cleaned up during namespace stop. Some of them
> increment use_count, some don't. This set fixes this discrepancy,
> i.e. now all such objects increment the use_count.
> 
> Though, the use_count itself is used in a very debug manner and checked
> only during namespace stop. So, I have placed it under
> NETNS_REFCNT_DEBUG definition exactly like this is done for socket
> refcounting code to remove extra atomic from any possible fast paths.
