Committer notes:
Added missing #include <unistd.h> for the close() prototype to fix this
on Alma Linux 8:
1 21.54 almalinux:8 : FAIL gcc version 8.5.0 20210514 (Red Hat 8.5.0-16) (GCC)
util/print-events.c: In function 'print_tracepoint_events':
util/print-events.c:103:4: error: implicit declaration of function 'close'; did you mean 'clone'? [-Werror=implicit-function-declaration]
close(evt_fd);
^~~~~
clone
Also use the newly added scandirat feature test to check if that
function is available, providing a HAVE_SCANDIRAT_SUPPORT conditional
warning to the user if it isn't available.

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.
