For users of perf-sys.h outside perf, e.g. samples/bpf/bpf_load.c, it's convenient not to depend on test_attr__*. After commit91854f9a07("perf tools: Move everything related to sys_perf_event_open() to perf-sys.h"), all users of perf-sys.h will depend on test_attr__enabled and test_attr__open. This commit enables a user to define HAVE_ATTR_TEST to zero in order to omit the test dependency.

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.
