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" * 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
