Andi Kleen 4b6ac811bc perf script: Handle missing fields with -F +..
When using -F + syntax to add a field the existing defaults are
currently all marked user_set. This can cause errors when some field is
missing in the perf.data

This patch tracks the actually user set fields separately, so that we don't
error out in this case.

Before:

  % perf record true
  % perf script -F +metric
  Samples for 'cycles:ppp' event do not have CPU attribute set. Cannot print 'cpu' field.
  %

After:

  5 perf record true
  % perf script -F +metric
              perf 28936 278636.237688:          1 cycles:ppp:  ffffffff8117da99 perf_event_exec+0x59 (/lib/modules/4.20.0-odilo/build/vmlinux)

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.
