* All these functions give the guarantee that parities are written
* in order. First parity P, then parity Q, and so on.
* This allows to specify the same memory buffer for multiple parities
* knowing that you'll get the latest written one.
* This characteristic is used by the raid_delta_gen() function to
* avoid damaging unused parities during recovery.
*
* @nd Number of data blocks
* @size Size of the blocks pointed to by @vv. It must be a multiple of 64.
