Replace a global map->crush_workspace (protected by a global mutex) with a list of workspaces, up to the number of CPUs + 1. This is based on a patch from Robin Geuze <robing@nl.team.blue>. Robin and his team have observed a 10-20% increase in IOPS on all queue depths and lower CPU usage as well on a high-end all-NVMe 100GbE cluster. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
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.
