Passing new arguments by value to the visitor callbacks is extremely inflexible for stuffing new parameters used by only some of the visitors. Use a context structure instead and pass the pointer through to the visitor callback. While at it, redefine the 'flags' parameter to the visitor to contain the bit indicating the phase of the walk. Pass the entire set of flags through the context structure such that the walker can communicate additional state to the visitor callback. No functional change intended.

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.
