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"
* tag 'md/4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md:
md: set rotational bit
raid6/test/test.c: bug fix: Specify aligned(alignment) attributes to the char arrays
raid5: handle register_shrinker failure
raid5: fix to detect failure of register_shrinker
md: fix a potential deadlock
md/bitmap: fix wrong cleanup
raid5: allow arbitrary max_hw_sectors
lib/raid6: Add AVX512 optimized xor_syndrome functions
lib/raid6/test/Makefile: Add avx512 gen_syndrome and recovery functions
lib/raid6: Add AVX512 optimized recovery functions
lib/raid6: Add AVX512 optimized gen_syndrome functions
md-cluster: make resync lock also could be interruptted
md-cluster: introduce dlm_lock_sync_interruptible to fix tasks hang
md-cluster: convert the completion to wait queue
md-cluster: protect md_find_rdev_nr_rcu with rcu lock
md-cluster: clean related infos of cluster
md: changes for MD_STILL_CLOSED flag
md-cluster: remove some unnecessary dlm_unlock_sync
md-cluster: use FORCEUNLOCK in lockres_free
md-cluster: call md_kick_rdev_from_array once ack failed
