Arnaldo Carvalho de Melo dd1a50377c perf trace: Introduce filter_loop_pids()
No change in functionality, just to make clearer that what we want when
filtering the tracer pid in a system wide tracing session is to avoid a
feedback loop.

This also paves the way for a more interesting loop avoidance algorithm,
one that tries to figure out if we are in a ssh session, xterm, etc.

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.
