  10           involving the host CPU.  Currently, this framework can be

  12           RAID operations in the MD driver.  This menu only presents

 437           This allows the async_tx api to take advantage of offload engines for
 438           memcpy, memset, xor, and raid6 p+q operations.  If your platform has
 439           a dma engine that can perform raid operations and you have enabled
 440           MD_RAID456 say Y.
 441
 442           If unsure, say N.
