Revised AVX-512 xor_gen() Implementation For Linux RAID Yielding More Performance Gains

A few days back I wrote about Google’s Eric Biggers spearheading an AVX-512 implementation of xor_gen() as the Linux kernel function used for generating and validating parity blocks such as for RAID5/RAID6. That initial implementation was yielding up to 41% better performance while a new implementation has now been posted for scoring some additional victories… https://www.phoronix.com/news/AVX-512-Xor-Gen-More-Perf
