In preparation for introducing a filesystem-level keyring which will contain fscrypt master keys, rename the existing 'struct fscrypt_master_key' to 'struct fscrypt_direct_key'. This is the structure in the existing table of master keys that's maintained to deduplicate the crypto transforms for v1 DIRECT_KEY policies. I've chosen to keep this table as-is rather than make it automagically add/remove the keys to/from the filesystem-level keyring, since that would add a lot of extra complexity to the filesystem-level keyring.

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.
