This patch renames the (never officially released) sysfs-knobs "blocked_hw" and "blocked_sw" to "hard" and "soft", as the hardware vs software conotation is misleading. It also gets rid of not needed locks around u32-read-access. Signed-off-by: Florian Mickler <florian@mickler.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
