Namhyung Kim be5863b7d9 perf top: Fix event group with more than two events
The event group feature links relevant hist entries among events so that
they can be displayed together.  During the link process, each hist
entry in non-leader events is connected to a hist entry in the leader
event.  This is done in order of events specified in the command line so
it assumes that events are linked in the order.

But 'perf top' can break the assumption since it does the link process
multiple times.  For example, a hist entry can be in the third event
only at first so it's linked after the leader.  Some time later, second
event has a hist entry for it and it'll be linked after the entry of the
third event.

This makes the code compilicated to deal with such unordered entries.
This patch simply unlink all the entries after it's printed so that they
can assume the correct order after the repeated link process.  Also it'd
be easy to deal with decaying old entries IMHO.

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.
