ftrace_module_init happen after dynamic_debug_setup, it is desired that cleanup should be called after this label however in current implementation it is called in free module label,ie:even though ftrace in not initialized, from so many fail case ftrace_release_mod() will be called and unnecessary traverse the whole list. In below patch we moved ftrace_release_mod() from free_module label to ddebug_cleanup label. that is the best possible location, other solution is to make new label to ftrace_release_mod() but since ftrace_module_init() is not return with minimum changes it should be in ddebug_cleanup label.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
