Patch series "Cleanup for memfd_create()", v4. memfd_create() handles all of its logic in a single function. Some of the logic in the function is also somewhat contrived (i.e. copying the memfd name from userpace). This series aims to cleanup memfd_create() by splitting out the logic into helper functions, and simplifying the memfd name copying to make the code easier to follow. This has no intended functional changes. Thank you Alice and Lorenzo for reviewing v3 of this series and for your feedback! This patch (of 2): memfd_create() is a pretty busy function that could be easier to read if some of the logic was split out into helper functions. Therefore, split the flags sanitization, name allocation, and file structure allocation into their own helper functions. No functional change.

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.
