Compiling a kernel with both FAIR_GROUP_SCHED=n and RT_GROUP_SCHED=n will generate a compiler warning: kernel/sched/core.c: In function 'sched_init': kernel/sched/core.c:5906:32: warning: variable 'ptr' set but not used It is unnecessary to have both "alloc_size" and "ptr", so just combine them.

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.
