[RW] If the device is registered for writeback throttling, then

- is exceeded in a given window of time (see wb_window_usec), then
+ is exceeded in a given window of time (see curr_win_nsec), then
the writeback throttling will start scaling back writes. Writing
a value of '0' to this file disables the feature. Writing a
value of '-1' to this file resets the value to the default
