From c55703d807a8c6c239a5fea7b9cd7da08c27d7a9 Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Wed, 6 Feb 2008 19:25:08 -0600 Subject: [PATCH] 9p: fix bug in attach-per-user When a new user attached at a directory other than the root, he would end up in the parent directory of the cwd. This was due to a logic error in the code which attaches the user at the mount point and walks back to the cwd. This patch fixes that.
