The crashk_low_res should be considered by /sys/kernel/kexec_crash_size to support two crash kernel regions shrinking if existing. While doing it, crashk_low_res will only be shrunk when the entire crashk_res is empty; and if the crashk_res is empty and crahk_low_res is not, change crashk_low_res to be crashk_res.

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.
