From ee61abb3223e28a1a14a8429c0319755d20d3e40 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 20 Jan 2013 20:22:58 -0800 Subject: module: fix missing module_mutex unlock Commit 1fb9341ac348 ("module: put modules in list much earlier") moved some of the module initialization code around, and in the process changed the exit paths too. But for the duplicate export symbol error case the change made the ddebug_cleanup path jump to after the module mutex unlock, even though it happens with the mutex held. Rusty has some patches to split this function up into some helper functions, hopefully the mess of complex goto targets will go away eventually.
