Currently the registration of the fsverity sysctls happens in signature.c, which couples it to CONFIG_FS_VERITY_BUILTIN_SIGNATURES. This makes it hard to add new sysctls unrelated to builtin signatures. Also, some users have started checking whether the directory /proc/sys/fs/verity exists as a way to tell whether fsverity is supported. This isn't the intended method; instead, the existence of /sys/fs/$fstype/features/verity should be checked, or users should just try to use the fsverity ioctls. Regardless, it should be made to work as expected without a dependency on CONFIG_FS_VERITY_BUILTIN_SIGNATURES. Therefore, move the sysctl registration into init.c. With CONFIG_FS_VERITY_BUILTIN_SIGNATURES, nothing changes. Without it, but with CONFIG_FS_VERITY, an empty list of sysctls is now registered.

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.
