Jakub Kicinski says: ==================== rtnetlink: avoid a warning in rtnl_newlink() I've been hoping for some time that someone more competent would fix the stack frame size warning in rtnl_newlink(), but looks like I'll have to take a stab at it myself :) That's the only warning I see in most of my builds. First patch refactors away a somewhat surprising if (1) code block. Reindentation will most likely cause cherry-pick problems but OTOH rtnl_newlink() doesn't seem to be changed often, so perhaps we can risk it in the name of cleaner code? Second patch fixes the warning in simplest possible way. I was pondering if there is any more clever solution, but I can't see it.. rtnl_newlink() is quite long with a lot of possible execution paths so doing memory allocations half way through leads to very ugly results. ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
