Luis Chamberlain 996ef312f2 sysctl: remove empty dev table
Now that all the dev sysctls have been moved out we can remove the
dev sysctl base directory. We don't need to create base directories,
they are created for you as if using 'mkdir -p' with register_syctl()
and register_sysctl_init(). For details refer to sysctl_mkdir_p()
usage.

We save 90 bytes with this changes:

./scripts/bloat-o-meter vmlinux.2.remove-sysctl-table vmlinux.3-remove-dev-table

Total: Before=21257057, After=21256967, chg -0.00%

The empty dev table has been in place since the v2.5.0 days because
back then ordering was essentialy. But later commit 7ec66d0636
("sysctl: Stop requiring explicit management of sysctl directories"),
merged as of v3.4-rc1, the entire ordering of directories was replaced
by allowing sysctl directory autogeneration. This new mechanism
introduced on v3.4 allows for sysctl directories to automatically be
created for sysctl tables when they are needed and automatically removes
them when no sysctl tables use them. That commit also added a dedicated
struct ctl_dir as a new type for these autogenerated directories.

README

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.
