This function will be useful later as the driver will need to retroactively create RIFs for new uppers with addresses. Add another helper that assumes RCU lock, and restructure the code to skip the IPv6 branch not through conditioning on the addr_list_empty variable, but by directly returning the result value. This makes the skip more obvious than it previously was. Signed-off-by: Petr Machata <petrm@nvidia.com> Reviewed-by: Amit Cohen <amcohen@nvidia.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
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.
