Alexey Budankov 06dc5bf21f perf tests: Check that complex event name is parsed correctly 
Extend regression testing to cover case of complex event names enabled
by the cset f92da71280 ("perf record: Enable arbitrary event names
thru name= modifier").

Testing it:

  # perf test
   1: vmlinux symtab matches kallsyms                       : Skip
   2: Detect openat syscall event                           : Ok
   3: Detect openat syscall event on all cpus               : Ok
   4: Read samples using the mmap interface                 : Ok
   5: Test data source output                               : Ok
   6: Parse event definition strings                        : Ok		<===!
   7: Simple expression parser                              : Ok
...

Committer testing:

  # perf test "event definition"
   6: Parse event definition strings                        : Ok

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.
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.
