Make the device-mapper layer pass through the derive_sw_secret,
import_key, generate_key, and prepare_key blk-crypto operations when all
underlying devices support hardware-wrapped inline crypto keys and are
passing through inline crypto support.
Commit ebc4176551 ("blk-crypto: add basic hardware-wrapped key
support") already made BLK_CRYPTO_KEY_TYPE_HW_WRAPPED be passed through
in the same way that the other crypto capabilities are. But the wrapped
key support also includes additional operations in blk_crypto_ll_ops,
and the dm layer needs to implement those to pass them through.
derive_sw_secret is needed by fscrypt, while the other operations are
needed for the new blk-crypto ioctls to work on device-mapper devices
and not just the raw partitions.

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.
