True. However:

 - The option already existed, was already using the "blocks" unit
   without mentioning how big a block is

 - The following patches in the series change this option to be a
   "size" rather than a number of blocks, which makes a lot more sense
   IMO. Especially since forcing 1KB blocks is really crappy.

Best regards,

Thomas
