From d8c8a9e36560e9ff4c99279d64ce5dd0e1a33fa6 Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Mon, 8 Feb 2010 16:23:23 -0600 Subject: 9p: fix option parsing Options pointer is being moved before calling kfree() which seems to cause problems. This uses a separate pointer to track and free original allocation.
