When PLTs are emitted at relocation time, we really should not exceed the number that we counted when parsing the relocation tables, and so currently, we BUG() on this condition. However, even though this is a clear bug in this particular piece of code, we can easily recover by failing to load the module. So instead, return 0 from module_emit_plt_entry() if this condition occurs, which is not a valid kernel address, and can hence serve as a flag value that makes the relocation routine bail out.

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.
