From f94b347059809aecd97af53a084fe5f3db045d92 Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Fri, 26 Jan 2007 00:57:04 -0800 Subject: [PATCH] 9p: fix bogus return code checks during initialization There is a simple logic error in init_v9fs - the return code checks are reversed. This patch fixes the return code and adds some messages to prevent module initialization from failing silently.
