Arnaldo Carvalho de Melo 2e2bbc039f perf tests: Avoid possible truncation with dirent->d_name + snprintf
Addressing a few cases spotted by a new warning in gcc 7:

  tests/parse-events.c: In function 'test_pmu_events':
  tests/parse-events.c:1790:39: error: '%s' directive output may be truncated writing up to 255 bytes into a region of size 90 [-Werror=format-truncation=]
     snprintf(name, MAX_NAME, "cpu/event=%s/u", ent->d_name);
                                       ^~

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.
