All those files are standalone programs that can be executed directly.
Some .py files were marked executable, others weren't, probably accidentally.
Mark them all as executable in preparation for subsequent changes.
Script for generating LOTS of SCSI disk and partition devices in
the fake sysfs we use for udev testing.
This script is supposed to be run after sys-script.py. It uses
code from sys-script.py as template to generate additional SCSI disk data
structures. Together with the "generator" code in udev-test.pl
added in the previous patch, it allows to run udev tests with almost
arbitrarily many devices, and thus to do performance scaling tests.
