Thanks for your mail, I have found a thread with the discussion and a patch for removing the wait_for_zero_refcount from module unloading, But not able to find this patch being merged on v3.13. (have checked all patches between 3.12 and 3.13) http://www.gossamer-threads.com/lists/linux/kernel/1783584?do=post_view_threaded#1783584 Thanks, Chetan Nanda > good luck, > > greg k-h >
