[ Upstream commit daff37f00c7506ca322ccfce95d342022f06ec58 ] The hw port ID of phy may change when inserting disks in batches, causing the port ID in hisi_sas_port and itct to be inconsistent with the hardware, resulting in I/O errors. The solution is to set the device state to gone to intercept I/O sent to the device, and then execute linkreset to discard and find the disk to re-update its information.

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.
