From ff49d74ad383f54041378144ca1a229ee9aeaa59 Mon Sep 17 00:00:00 2001 From: Yehuda Sadeh Date: Sat, 3 Jul 2010 13:07:35 +1000 Subject: module: initialize module dynamic debug later We should initialize the module dynamic debug datastructures only after determining that the module is not loaded yet. This fixes a bug that introduced in 2.6.35-rc2, where when a trying to load a module twice, we also load it's dynamic printing data twice which causes all sorts of nasty issues. Also handle the dynamic debug cleanup later on failure.
