hdparm and CONFIG_FEATURE_HDPARM_HDIO_GET_DMA ?

Hi there,

is there a reason why miscutils/Config.in does not contain an entry 
for CONFIG_FEATURE_HDPARM_HDIO_GET_DMA?

And should we rename the define into CONFIG_FEATURE_HDPARM_HDIO_DMA 
and use it for "set" and "get" ???

Since although CONFIG_FEATURE_HDPARM_HDIO_GET_DMA is _not_ set I still 
can use "hdparm -d 1 /dev/hda" to switch the DMA on.
Is this desireable or meant to be like that?

Thanks,

Steven
