mainlining shenanigans
51f382428c
Added callback option (-G) to support cgroups for 'perf top'.
Added condition to make sure -cgroup and --all-cgroups aren't both enabled.
Example:
$perf top -e cycles -G system.slice/docker-6b95a5eb649c0d671eba3835f0d93973d05a088f3ae8602246bde37affb1ba3e.scope -a --stdio

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.
