I thought that /proc/sysvipc has the same bug as /proc/net
commit 1fde6f21d90f8ba5da3cb9c54ca991ed72696c43
proc: fix /proc/net/* after setns(2)
However, it doesn't! /proc/sysvipc files do
get_ipc_ns(current->nsproxy->ipc_ns);
in their open() hook and avoid the problem.
Keep the test, maybe /proc/sysvipc will become broken someday :-\
