Merge tag 'md/4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md
Pull MD updates from Shaohua Li:
"This update includes:
- new AVX512 instruction based raid6 gen/recovery algorithm
- a couple of md-cluster related bug fixes
- fix a potential deadlock
- set nonrotational bit for raid array with SSD
- set correct max_hw_sectors for raid5/6, which hopefuly can improve
performance a little bit
- other minor fixes"
