Namhyung Kim 3fb29a7514 perf test: Skip perf probe tests when running as non-root
perf trace requires root because it needs to use [ku]probes.
Skip those test when it's not run as root.

Before:
  $ perf test probe
   47: Probe SDT events                                                : Ok
  104: test perf probe of function from different CU                   : FAILED!
  115: perftool-testsuite_probe                                        : FAILED!
  117: Add vfs_getname probe to get syscall args filenames             : FAILED!
  118: probe libc's inet_pton & backtrace it with ping                 : FAILED!
  119: Use vfs_getname probe to get syscall args filenames             : FAILED!

After:
  $ perf test probe
   47: Probe SDT events                                                : Ok
  104: test perf probe of function from different CU                   : Skip
  115: perftool-testsuite_probe                                        : Skip
  117: Add vfs_getname probe to get syscall args filenames             : Skip
  118: probe libc's inet_pton & backtrace it with ping                 : Skip
  119: Use vfs_getname probe to get syscall args filenames             : Skip

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 reStructuredText 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.
