The scheduler has this special SCHED_WARN() facility that depends on CONFIG_SCHED_DEBUG. Since CONFIG_SCHED_DEBUG is getting removed, convert SCHED_WARN() to WARN_ON_ONCE(). Note that the warning output isn't 100% equivalent: #define SCHED_WARN_ON(x) WARN_ONCE(x, #x) Because SCHED_WARN_ON() would output the 'x' condition as well, while WARN_ONCE() will only show a backtrace. Hopefully these are rare enough to not really matter. If it does, we should probably introduce a new WARN_ON() variant that outputs the condition in stringified form, or improve WARN_ON() itself.

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 reStructuredText 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.
