This causes test failures with slow throttle speeds on SSD devices. The first patch in the series fixes the problem by restoring the throttle slice time to a fixed value, matching behavior seen prior to above mentioned revert. The remaining patches clean up unneeeded code after removing CONFIG_BLK_DEV_THROTTLING_LOW.
