>From 0eeba453aaba0ebff86f0a7ad9bfb8afbde0c0dc Mon Sep 17 00:00:00 2001 From: Matthieu CASTET Date: Thu, 20 Jan 2011 21:25:03 +0100 Subject: [PATCH] Fix jump table in module init section If we use jump table in module init, there are marked as removed in __jump_table section after init is done. But we already applied ro permissions on the module, so we can't modify a read only section (crash in remove_jump_label_module_init). Make the __jump_table section rw.
