commit 2546da99212f22034aecf279da9c47cbfac6c981 upstream. The RX SGL in processing is already registered with the RX SGL tracking list to support proper cleanup. The cleanup code path uses the sg_num_bytes variable which must therefore be always initialized, even in the error code path.

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.
