Linux kernel source tree
53f3811dfd
This is a preparation commit to make it easy to remove the sentinel elements (empty end markers) from the ctl_table arrays. It both allows the systematic removal of the sentinels and adds the ctl_table_size variable to the stopping criteria of the list_for_each_table_entry macro that traverses all ctl_table arrays. Once all the sentinels are removed by subsequent commits, ctl_table_size will become the only stopping criteria in the macro. We don't actually remove any elements in this commit, but it sets things up to for the removal process to take place. By adding header->ctl_table_size as an additional stopping criteria for the list_for_each_table_entry macro, it will execute until it finds an "empty" ->procname or until the size runs out. Therefore if a ctl_table array with a sentinel is passed its size will be too big (by one element) but it will stop on the sentinel. On the other hand, if the ctl_table array without a sentinel is passed its size will be just write and there will be no need for a sentinel.

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.
