+Subject: [PATCH 22/27] hurd: add an Hurd server introspection protocol
+
+Most Hurd servers use libports to manage receive rights and the
+associated objects.  These procedures can be used to query the state
+associated with receive rights managed by libports.
+
+The procedures are not specific to libports.  Any Hurd server can
+implement this protocol.  To do so, a server installs a send right in
+the array of well-known ports, under the key
+HURD_PORT_REGISTER_INTROSPECTION.
+
+* hurd/hurd_port.defs: New file.
+* hurd/hurd_types.h (HURD_PORT_REGISTER_INTROSPECTION): New macro.
+(HURD_PORT_REGISTER_MAX): Likewise.
+* hurd/subsystems: Add hurd_port subsystem.
