This patch moves validate_linkmsg() out of do_setlink() to its callers and deletes the early validate_linkmsg() call in __rtnl_newlink(), so that it will not call validate_linkmsg() twice in either of the paths: - __rtnl_newlink() -> do_setlink() - __rtnl_newlink() -> rtnl_newlink_create() -> rtnl_create_link() Additionally, as validate_linkmsg() is now only called with a real dev, we can remove the NULL check for dev in validate_linkmsg(). Note that we moved validate_linkmsg() check to the places where it has not done any changes to the dev, as Jakub suggested.

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.
