Joe Stringer a26305363d perf test: Add libbpf pinning test
Add a test for the newly added BPF object pinning functionality.

For example:

  # tools/perf/perf test 37
    37: BPF filter                                 :
    37.1: Basic BPF filtering                      : Ok
    37.2: BPF pinning                              : Ok
    37.3: BPF prologue generation                  : Ok
    37.4: BPF relocation checker                   : Ok

  # tools/perf/perf test 37 -v 2>&1 | grep pinned
    libbpf: pinned map '/sys/fs/bpf/perf_test/flip_table'
    libbpf: pinned program '/sys/fs/bpf/perf_test/func=SyS_epoll_wait/0'

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
