Mainline Linux tree for various devices, only for fun :)

For auto-control irq affinity mode, choose the dq to deliver IO according to the current CPU. Then it decreases the performance regression that fio and CQ interrupts are processed on different node. For user control irq affinity mode, keep it as before. To realize it, also need to distinguish the usage of dq lock and sas_dev lock. We mark as experimental due to ongoing discussion on managed MSI IRQ during hotplug: https://marc.info/?l=linux-scsi&m=154876335707751&w=2 We're almost at the point where we can expose multiple queues to the upper layer for SCSI MQ, but we need to sort out the per-HBA tags performance issue.

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.
