Kmemleak ia a memory leak checker. KASAN is also a memory checker but it focuses more on finding out-of-bounds and use-after-free bugs. Since kmemleak is inherently slow especially on systems with large number of CPUs, adding KASAN instrumentation will make it slower even more. As kmemleak is not for production use, the utility of enabling KASAN there is questionable. This patch disables KASAN instrumentation for configurations that enable both of them to slightly reduce performance overhead.

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.
