I had to spend some (a lot;) time to understand why pidfd_info_test (and more) fails with my patch under qemu on my machine ;) Until I applied the patch below. I think it is a bad idea to do the things like #ifndef __NR_clone3 #define __NR_clone3 -1 #endif because this can hide a problem. My working laptop runs Fedora-23 which doesn't have __NR_clone3/etc in /usr/include/. So "make" happily succeeds, but everything fails and it is not clear why.

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.
