Currently, the sense data reporting feature set is enabled for all ATA
devices which supports the feature set (ata_id_has_sense_reporting()),
see ata_dev_config_sense_reporting().
However, even if sense data reporting is enabled, and the device
indicates that sense data is available, the sense data is only fetched
for ATA ZAC devices. For regular ATA devices, the available sense data
is never fetched, it is simply ignored. Instead, libata will use the
ERROR + STATUS fields and map them to a very generic and reduced set
of sense data, see ata_gen_ata_sense() and ata_to_sense_error().
When sense data reporting was first implemented, regular ATA devices
did fetch the sense data from the device. However, this was restricted
to only ATA ZAC devices in commit

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.
