Modify ata_scsiop_mode_sense() and ata_msense_control() to support mode sense access to the T2A and T2B sub-pages of the control mode page. ata_msense_control() is modified to support sub-pages. The T2A sub-page is generated using the read descriptors of the command duration limits log page 18h. The T2B sub-page is generated using the write descriptors of the same log page. With the addition of these sub-pages, getting all sub-pages of the control mode page is also supported by increasing the value of ATA_SCSI_RBUF_SIZE from 576B up to 2048B to ensure that all sub-pages fit in the fill buffer.

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.
