In the next patch, we are going to add optional dump of exceptions to rt6_dump_route(). Change the return code of rt6_dump_route() to accomodate partial node dumps: we might dump multiple routes per node, and might be able to dump only a given number of them, so fib6_dump_node() will need to know how many routes have been dumped on partial dump, to restart the dump from the point where it was interrupted. Note that fib6_dump_node() is the only caller and already handles all non-negative return codes as success: those become -1 to signal that we're done with the node. If we fail, return 0, as we were unable to dump the single route in the node, but we're not done with it.

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.
