Arnaldo Carvalho de Melo 4975223b81 perf tools: Introduce rlimit__bump_memlock() helper
Just like the BPF guys did when faced with failures with map creation,
etc, i.e. their solution is:

  tools/testing/selftests/bpf/bpf_rlimit.h

For perf use this function in 'perf test' and in 'perf trace'.

Make it bump to 4 times the current value, if it fails twice the current
value and if it still fails, warn that things like BPF map creation may
fail, to help in diagnosing the problem.

README

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.
