Now ata devices attached with sas controller do not have transport class, so that we can not see any information of these ata devices in /sys/class/ata_port(or ata_link or ata_device). Add transport class for the ata devices attached with sas controller. The /sys/class directory will show the infomation of the ata devices as follows: localhost:/sys/class # ls ata* ata_device: dev1.0 dev2.0 ata_link: link1 link2 ata_port: ata1 ata2 No functional change of the device scanning and io path. The ata transport class was deleted when destroying the sas devices.

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
