Linux kernel source tree
6e16f51335
thuge-gen was previously only munmapping part of the mmapped buffer, which caused us to run out of 1G huge pages for a later part of the test. Fix this by munmapping the whole buffer. Based on the code, it looks like a typo rather than an intention to keep some of the buffer mapped. thuge-gen was also calling mmap with SHM_HUGETLB flag (bit 11 set), which is actually MAP_DENYWRITE in mmap context. The man page says this flag is ignored in modern kernels. I'm pretty sure from the context that the author intended to pass the MAP_HUGETLB flag so I've fixed that up too.

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.
