Lee, Chun-Yi 27664c5818 ACPI / scan: Send change uevent with offine environmental data
In current design of ACPI container offline, Kernel emits
KOBJ_CHANGE uevent to user space to indidate that the ejection of
the container was triggered by platform. (caa73ea15 patch)

A pure KOBJ_CHANGE uevent is not enough for user space to identify
the purpose. For example, a "udevadm trigger" command can also
be used to emit change event to all udev rules. A udev rule can not
identify that the event is from kernel for offline or from udevadm
for other purpose. Then the offline action in udev rule may also be
triggered by udevadm tool.

So, similar to the change uevent of dock, kernel sends the
KOBJ_CHANGE uevent with a offline environmental data to indicate
purpose. It's useful by udev rule for using ENV{EVENT} filter.

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.
