sparse warns about a large memset() call within zcrypt_device_status_mask_ext(): drivers/s390/crypto/zcrypt_api.c:1303:15: warning: memset with byte count of 262144 Get rid of this warning by making sure that all callers of this function allocate memory with __GFP_ZERO, which zeroes memory already at allocation time, which again allows to remove the memset() call.

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.
