If the message is directed at the system administrator, then it would
be nice if there were some more meaningful way to show the namespace
that is affected than just printing the hex address of the kernel structure.

As the sysadmin for my test systems, printing the hex address is mildly
annoying ... I now have to add a new case to my scripts that look at
dmesg output for unusual activity.

Is there some better "name for a namespace" than the address? Perhaps
the process id of the process that instantiated the namespace???
