2013-03-18test_power: Fix a bug in setting module parameter valuesAndrey Gelman
When the kernel loads a module, module params are processed prior to calling module_init. As a result, setting module param value should not have side effects, at least as long as the module has not been initialized.

2011-05-20power: Make test_power driver more dynamic.John Stultz
In 2008 Masashi YOKOTA <yokota@pylone.jp> created the virtual battery driver found here: http://downloads.pylone.jp/src/virtual_battery/virtual_battery-0.0.1.tar.bz2 It found use out of tree, but was never merged upstream. Since then the test_power driver has been merged, which provides very similar functionality. This patch extends the test_power driver to be more dynamic at runtime, by merging portions of the Virtual Battery Driver by Masashi YOKOTA. With this patch, I can tweak the values in: /sys/module/test_power/parameters/* and watch the behavior of the gnome power managment daemon or other battery UI software.
