From f39335453fe79f4e12e263e7c6387dc9fb86bfff Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Wed, 6 Feb 2008 19:25:04 -0600 Subject: [PATCH] 9p: add remove function to trans_virtio Request from rusty: Just cleaning up patches for 2.6.25 merge, and noticed that net/9p/trans_virtio.c doesn't have a remove function. This will crash when removing the module (console doesn't have one because it can't really be removed).
