From 4d10380e720a3ce19dbe88d0133f66ded07b6a8f Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Thu, 19 May 2011 16:55:25 -0600 Subject: [PATCH] module: zero mod->init_ro_size after init is freed. Reset mod->init_ro_size to zero after the init part of a module is unloaded. Otherwise we need to check if module->init is NULL in the unprotect functions in the next patch.
