commit 6963c508fd7ab66ae0b7ae3db9a62ca6267f1ae8 upstream.
The current behavior is to accept any strings as inputs, this results in
an inconsistent result where an unexisting scheduler can be set:
# sysctl -w net.mptcp.scheduler=notdefault
net.mptcp.scheduler = notdefault
This patch changes this behavior by checking for existing scheduler
before accepting the input.
Fixes: e3b2870b6d ("mptcp: add a new sysctl scheduler")

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.
