MPT Fusion adapters can steer completions to individual queues and we now have support for shared host-wide tags in the I/O stack. The addition of the host-wide tags allows us to enable multiqueue support for MPT Fusion adapters. Once host-wise tags are enabled, the CPU hotplug feature is also supported. Allow use of host-wide tags to be disabled through the "host_tagset_enable" module parameter. Once we do not have any major performance regressions using host-wide tags, we will drop the hand-crafted interrupt affinity settings. Performance is meeting expectations. About 3.1M IOPS using 24 Drive SSD on Aero controllers.

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.
