From 4f4038328da5eb9cc237b51d3fe68138fd3fea14 Mon Sep 17 00:00:00 2001 From: Abhishek Kulkarni Date: Sun, 19 Jul 2009 13:41:53 -0600 Subject: 9p: Fix v9fs show_options Add the delimiter ',' before the options when they are passed and check if no option parameters are passed to prevent displaying NULL in /proc/mounts.
