- Replace the ATA_DFLAG_ZAC device flag with the helper function
ata_dev_is_zac() testing directly the device class and device zoned
mode (me).
- Some small cleanup of ata_scsi_offline_dev() code (me).
- Improve the description of the link power management (LPM) policies
in Kconfig and in the comments defining these. Together with this,
clarify the description of the ahci driver mobile_lpm_policy module
parameter (me).
- Various code refactoring of libata LPM handling (ata_eh_set_lpm()
renaming, introduce ata_dev_config_lpm(), LPM related quirk handling,
and LPM related feature advertizing on device scan) (me).
- Avoid unnecessary device reset when revalidating after an error when
LPM is used (me).
- Do not allow setting a port/link LPM policy if LPM is not supported,
either because the controller does not support partial, slumber nor
devsleep, or when the port is an external port with hotplug
capability (me).
- Make sure that device initiated power management (DIPM) is not
enabled if the host (controller) lacks support for this feature (me).
- Improve messages and debug messages related to LPM, in particular,
reduce the number of messages signaling the lack of LPM support (me).
- Cache in memory a device general purpose log directory to avoid
having to access this log for every log page access. The intent here
is to reduce the number of read log commands when scanning or
revalidating a device (me).
- Change ata_dev_cleanup_cdl_resources() to be a static function (me).
- Rename and simplify the mode setting functions (me).
- Introduce the helper function ata_port_eh_scheduled() to check if EH
is pending or running for a port (me)
- Improve ata_eh_set_pending() (return bool instead of int) (me).
- Use sysfs_emit() instead of scnprintf() for libata-transport
attributes (Jonathan).
- Use the existing macro definiton of RDC vendor ID instead of
hardcoding it in the pata_rdc driver (Andy).
- Rework how EH is called for a port to avoid needing to pass along the
prereset, softreset, hardreset and postreset operations. The
driver API documentation for this is also updated (me).

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 reStructuredText 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.
