I can't reproduce it:

$ while :; do ./bind_netlink 10000 12345; done
Ports successfully created, terminating
Create 10000 ports
Created 1000 ports
Created 2000 ports
Created 3000 ports
Created 4000 ports
Created 5000 ports
Created 6000 ports
Created 7000 ports
Created 8000 ports
Created 9000 ports
Created 10000 ports
Ports successfully created, terminating
...

So what am I missing?

Thanks,

I can't speak for netlink, but if you apply patch 1/3 from this thread,
test_rhashtable.c starts generating many insert failures during the
multiple thread test.

Cheers, Phil
