greg@kroah.com 724257d97b [PATCH] add support for figuring out which device on the sysfs "chain" the rule applies to.
This should fix one of the more annoying things to me about udev, and
gets rid of a TODO item.

# udev-test
#
# Provides automated testing of the udev binary.
# The whole test is self contained in this file, except the matching sysfs tree.
# Simply extend the @tests array, to add a new test variant.
#
# Every test is driven by its own temporary config file.
# This program prepares the environment, creates the config and calls udev.
#
# udev reads the config, looks at the provided sysfs and
# first creates and then removes the device node.
# After creation and removal the result is checked against the
# expected value and the result is printed.
#
# happy testing,
