LTP memfd_create04 started failing for some huge page sizes
after v5.4-10135-gc3bfc5dd73c6.
The problem is the check introduced to for_each_hstate() loop that
should skip default_hstate_idx. Since it doesn't update 'i' counter,
all subsequent huge page sizes are skipped as well.

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.
