Subject: /proc/sys/user/max_time_namespaces?

Dmitry, Andrei

[Andrei, I mistyped your openvz address in an email of a few minutes
ago ("[PATCH] ns: Fix time_for_children symlink"). You were CCed
on your gmail address though.]

In the namespaces(7) manual page there is documentation for 
these files:

$ ls -1 /proc/sys/user/*namespaces
/proc/sys/user/max_cgroup_namespaces
/proc/sys/user/max_ipc_namespaces
/proc/sys/user/max_mnt_namespaces
/proc/sys/user/max_net_namespaces
/proc/sys/user/max_pid_namespaces
/proc/sys/user/max_user_namespaces
/proc/sys/user/max_uts_namespaces

These files allow one to limit on the number of namespaces
of each type.

However, there is no /proc/sys/user/max_time_namespaces file.
Was this deliberate, or an oversight?

Thanks,

Michael
