Currently, after allocating an sk_buff, driver fills the sk_buff within code block guarded by a NULL check on the sk_buff. If a NULL check is done immediately after the allocation, and code returns on error, then the subsequent code need not be guarded and the level of indentation may be reduced. This aids the readability of the code and makes explicit the error path. Check for NULL directly after allocating the sk_buff, return if allocation fails. Reduce indentation of subsequent code. Do not change the program logic. Signed-off-by: Tobin C. Harding <me@tobin.cc> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
