Replace SIZE_MAX with ARRAY_SIZE in the register_net_sysctl macro. Now that all the callers to register_net_sysctl are actual arrays, we can call ARRAY_SIZE() without any compilation warnings. By calculating the actual array size, this commit is making sure that register_net_sysctl and all its callers forward the table_size into sysctl backend for when the sentinel elements in the ctl_table arrays (last empty markers) are removed. Without it the removal would fail lacking a stopping criteria for traversing the ctl_table arrays. Stopping condition continues to be based on both table size and the procname null test. This is needed in order to allow for the systematic removal al the sentinel element in subsequent commits: Before removing sentinel the stopping criteria will be the last null element. When the sentinel is removed then the (correct) size will take over.

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.
