There are some machines with slow disk and fast CPUs. When they are under memory pressure, it could take a long time to swap before the OOM kicks in to free up some memory. As the results, it needs a large mem pool for kmemleak or suffering from higher chance of a kmemleak metadata allocation failure. 524288 proves to be the good number for all architectures here. Increase the upper bound to 1M to leave some room for the future.

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.
