struct virtio_crypto_[as]kcipher_ctx contains a backpointer to struct crypto_[as]kcipher which is superfluous in two ways: First, it's not used anywhere. Second, the context is embedded into struct crypto_tfm, so one could just use container_of() to get from the context to crypto_tfm and from there to crypto_[as]kcipher. Drop the superfluous backpointer. Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
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.
