[ Upstream commit 7005227369 ]
When NFSD_V4 is enabled and CRYPTO is disabled,
Kbuild gives the following warning:
WARNING: unmet direct dependencies detected for CRYPTO_SHA256
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- NFSD_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFSD [=y] && PROC_FS [=y]
WARNING: unmet direct dependencies detected for CRYPTO_MD5
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- NFSD_V4 [=y] && NETWORK_FILESYSTEMS [=y] && NFSD [=y] && PROC_FS [=y]
This is because NFSD_V4 selects CRYPTO_MD5 and CRYPTO_SHA256,
without depending on or selecting CRYPTO, despite those config options
being subordinate to CRYPTO.

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.
