Linux kernel source tree

Though vmcoreinfo is intended to be small, at just one page, useful information is still added to it, so we risk running out of space. Currently there is no runtime check to see whether the vmcoreinfo buffer has been exhausted. Add a warning for this case. Currently, my static checking tool[1] indicates that a good upper bound for vmcoreinfo size is currently 3415 bytes, but the best time to add warnings is before the risk becomes too high.

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.
