Currently, the srcu_funnel_gp_start() walks its local variable snp up the tree and reloads sdp->mynode whenever it is necessary to check whether it is still at the leaf srcu_node level. This works, but is a bit more obtuse than absolutely necessary. In addition, upcoming commits will dynamically size srcu_struct structures, in which case sdp->mynode will no longer necessarily be a constant, and this commit helps prepare for that dynamic sizing.

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.
