This patch removes most of the debug code which is build in when CONFIG_ZCRYPT_DEBUG is enabled. There is no real exploiter for this code any more and at least one ioctl fails with this code enabled. The CONFIG_ZCRYPT_DEBUG kernel config option still makes sense as some debug sysfs entries can get enabled with this and maybe long term a new better designed debug and error injection way will get introduced. This patch only removes code surrounded by the named kernel config option. This option should by default always be off anyway. The structs and defines removed by the patch have been used only by code surrounded by a CONFIG_ZCRYPT_DEBUG ifdef and thus can be removed also. In the end this patch removes all the failure-injection possibilities which had been available when the kernel had been build with CONFIG_ZCRYPT_DEBUG. It has never been used that much and was too unflexible anyway.

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.
