+--------------------------------------------------------------------------
+These files provides information about the namespaces within which the process
+is contained. The files named only with the namespace type <nstype> contain a
+link that lists the containing namespace' inode number in its proc filesystem.
+The files with suffix _snum contain a link that lists the containing
+namespace' instance serial number, unique per kernel since boot. The
+namespace types are self-describing.

+The output format of the inode links is:

+The output format of the serial number links is:
