This patch adds the module parameter "refreshrate" to set delay for
the deferred io. The refresh rate is given in units of Hertz. The
default refresh rate is 1 Hz. The refresh rate set through the
newly introduced parameter applies to all instances of the driver
and for now it is not possible to change it individually.

It's written the wrong way and the right way in the same line :) Of
course I will fix that.

Thanks,
