Song Liu 65074d43fc perf/core: Prepare perf_event.h for new types: 'perf_kprobe' and 'perf_uprobe'
Two new perf types, perf_kprobe and perf_uprobe, will be added to allow
creating [k,u]probe with perf_event_open. These [k,u]probe are associated
with the file decriptor created by perf_event_open(), thus are easy to
clean when the file descriptor is destroyed.

kprobe_func and uprobe_path are added to union config1 for pointers to
function name for kprobe or binary path for uprobe.

kprobe_addr and probe_offset are added to union config2 for kernel
address (when kprobe_func is NULL), or [k,u]probe offset.

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.
