Since 75562573bab3 ("perf tools: Add support for
PERF_SAMPLE_IDENTIFIER") we don't need explicitely set
PERF_SAMPLE_IDENTIFIER, as perf_evlist__config() will do this for us,
i.e. when there are more than one evsel in an evlist, it will check if
some evsel has a sample_type different than the one on the first evsel
in the list, setting PERF_SAMPLE_IDENTIFIER in that case.
So, to simplify 'perf trace' codebase, ditch that check.

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.
