Wrapped keys can have key sizes of variable length.
Pass in the wrapped key size sent from userspace instead
of using a fixed value from the cipher when calling into
blk-crypto.
Bug: 156230001
Test: Validated metadata encryption with wrappedkey_v0 when /data
is mounted on a dm device.
fstab: metadata_encryption=aes-256-xts:wrappedkey_v0

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
