• 7056741fd   lib/raid6: Add AVX2 optimized recovery functions ... Browse Code »

  Optimize RAID6 recovery functions to take advantage of
  the 256-bit YMM integer instructions introduced in AVX2.

  The patch was tested and benchmarked before submission.
  However hardware is not yet released so benchmark numbers
  cannot be reported.
