From 20f9acdd40770065b994f3f58a7fcda32064a6cc Mon Sep 17 00:00:00 2001
From: Miles Bader <miles@gnu.org>
Date: Thu, 2 Nov 1995 22:58:58 +0000
Subject: (fshelp_start_translator_long, service_fsys_startup):   Change to use
 a callback function instead of passing the actual node.
 (service_fsys_startup): Support the open flags coming from the translator.
 (struct fsys_startup_request): Add the flags field. (flagsCheck): New
 variable.
