Charlie Jenkins <charlie@rivosinc.com> says: Ard brought this to my attention in this patch [1]. I benchmarked this patch on the Nezha D1 (which does not contain Zba or Zbkb so it uses the default algorithm) by navigating through a large directory structure. I created a 1000-deep directory structure and then cd and ls through it. With this patch there was a 0.57% performance improvement.

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.
