Looks like a remove_dir/create_dir race ..

        free_user()                     alloc_uid()

           uid_hash_remove(up);

                                        uid_hash_insert(new, hashent);

           schedule_work()
                                        user_kobject_create();
                                        kobject_add();  -> Boom!

           remove_user_sysfs_dir();

/me looks up sysfs programming examples ..
