With sanitizers enabled, this function uses a lot of stack, causing a harmless warning: lib/test_objagg.c: In function 'test_hints_case.constprop': lib/test_objagg.c:994:1: error: the frame size of 1440 bytes is larger than 1408 bytes [-Werror=frame-larger-than=] Most of this is from the two 'struct world' structures. Since most of the work in this function is duplicated for the two, split it up into separate functions that each use one of them. The combined stack usage is still the same here, but there is no warning any more, and the code is still safe because of the known call chain.

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.
