+Description:
+               (RW) For a device supporting the command duration limits
+               feature, write to the file to turn on or off the feature.
+               By default this feature is turned off.
+               Writing "1" to this file enables the use of command duration
+               limits for read and write commands in the kernel and turns on
+               the feature on the device. Writing "0" disables the feature.
