With one exception, the internal key size constants such as FS_AES_256_XTS_KEY_SIZE are only used for the 'available_modes' array, where they really only serve to obfuscate what the values are. Also some of the constants are unused, and the key sizes tend to be in the names of the algorithms anyway. In the past these values were also misused, e.g. we used to have FS_AES_256_XTS_KEY_SIZE in places that technically should have been FS_MAX_KEY_SIZE. The exception is that FS_AES_128_ECB_KEY_SIZE is used for key derivation. But it's more appropriate to use FS_KEY_DERIVATION_NONCE_SIZE for that instead. Thus, just put the sizes directly in the 'available_modes' array. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> |

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.
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.
