The ATA device flag ATA_DFLAG_ZAC is used to indicate if a devie is a host managed or host aware zoned device. However, this flag is not used in the hot path and only used during device scanning/revalidation and for inquiry and sense SCSI command translation. Save one bit from struct ata_device flags field by replacing this flag with the internal helper function ata_dev_is_zac(). This function returns true if the device class is ATA_DEV_ZAC (host managed ZAC device case) or if its identify data reports it supports the zoned command set (host aware ZAC device case).

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.
