Enable support for zoned block devices. This is done by: 1) implementing the target report_zones method. 2) adding the DM_TARGET_ZONED_HM flag to the target features. 3) setting DM_CRYPT_NO_WRITE_WORKQUEUE flag to avoid IO processing via workqueue. 4) Introducing inline write encryption completion to preserve write ordering. The last point is implemented by introducing the internal flag DM_CRYPT_WRITE_INLINE. When set, kcryptd_crypt_write_convert() always waits inline for the completion of a write request encryption if the request is not already completed once crypt_convert() returns. Completion of write request encryption is signaled using the restart completion by kcryptd_async_done(). This mechanism allows using ciphers that have an asynchronous implementation, isolating dm-crypt from any potential request completion reordering for these ciphers.

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.
