Arnaldo Carvalho de Melo bc055c54b8 perf symbols: Relax checks on perf-PID.map ownership
Those are simple enough, and usually not produced by root, instead by
whatever user is running java, rust, Node.js JIT code that end up
generating those /tmp/perf-PID.map for resolution of symbols in the
anonymous executable maps.

Having to use --force to resolve symbols in 'perf top' is a distraction,
as recently I experienced when node.js symbols were not being resolved
by 'perf top'.

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.
