ZBC Zoned Block Commands specification mandates SYNCHRONIZE CACHE(16) for
host-managed zoned block devices, but does not mandate SYNCHRONIZE
CACHE(10). Call SYNCHRONIZE CACHE(16) in place of SYNCHRONIZE CACHE(10) to
ensure that the command is always supported. For this purpose, add
use_16_for_sync flag to struct scsi_device in same manner as use_16_for_rw
flag.
To be precise, ZBC does not mandate SYNCHRONIZE CACHE(16) for host-aware
zoned block devices. However, modern devices should support 16-byte
commands. Hence, call SYNCHRONIZE CACHE (16) on both types of ZBC devices,
host-aware and host-managed. Of note is that READ(16) and WRITE(16) have
same story and they are already called for both types of ZBC devices.
Another note is that this patch depends on the fix commit

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.
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.
