It's handy to have an ldisc number free for out-of-tree testing. This way, a new ldisc can be developed on any running system, without having to recompile the kernel just to define a new number. This is the highest number (and also the last one) available under the old numbering scheme, so let's reserve it before it's too late. From now on, every new ldisc upstreamed will have to increment NR_LDISCS in lockstep with its addition to the table in tty.h.

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.
