From a8e63bff521f0387fb4f4e486dede0e78dca8f41 Mon Sep 17 00:00:00 2001 From: Latchesar Ionkov Date: Thu, 22 Sep 2005 21:43:51 -0700 Subject: [PATCH] v9fs: make copy of the transport prototype instead of using it directly When a new session is created it uses a template object of the specified transport type to instantiate its own copy. The code for the making a copy of the template object was lost, and the object itself is attached to the v9fs session. This leads to many sessions using the same transport instead of having their own copy. The patch puts back the code that makes a copy of the template object.
