Anton Protopopov says: ==================== Add a new benchmark for hashmap lookups and fix several typos. In commit 3 I've patched the bench utility so that now command line options can be reused by different benchmarks. The benchmark itself is added in the last commit 7. I was using this benchmark to test map lookup productivity when using a different hash function [1]. When run with --quiet, the results can be easily plotted [2]. The results provided by the benchmark look reasonable and match the results of my different benchmarks (requiring to patch kernel to get actual statistics on map lookups).

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.
