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 Thanks, Shaohua The following changes since commit 7d1e042314619115153a0f6f06e4552c09a50e13: Merge tag 'usercopy-v4.8-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux (2016-09-20 17:11:19 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shli/md.git tags/md/4.9-rc1 for you to fetch changes up to bb086a89a406b5d877ee616f1490fcc81f8e1b2b: md: set rotational bit (2016-10-03 10:20:27 -0700) ---------------------------------------------------------------- Chao Yu (1): raid5: fix to detect failure of register_shrinker Gayatri Kammela (5): lib/raid6: Add AVX512 optimized gen_syndrome functions lib/raid6: Add AVX512 optimized recovery functions lib/raid6/test/Makefile: Add avx512 gen_syndrome and recovery functions lib/raid6: Add AVX512 optimized xor_syndrome functions raid6/test/test.c: bug fix: Specify aligned(alignment) attributes to the char arrays Guoqing Jiang (9): md-cluster: call md_kick_rdev_from_array once ack failed md-cluster: use FORCEUNLOCK in lockres_free md-cluster: remove some unnecessary dlm_unlock_sync md: changes for MD_STILL_CLOSED flag md-cluster: clean related infos of cluster md-cluster: protect md_find_rdev_nr_rcu with rcu lock md-cluster: convert the completion to wait queue md-cluster: introduce dlm_lock_sync_interruptible to fix tasks hang md-cluster: make resync lock also could be interruptted Shaohua Li (5): raid5: allow arbitrary max_hw_sectors md/bitmap: fix wrong cleanup md: fix a potential deadlock raid5: handle register_shrinker failure md: set rotational bit arch/x86/Makefile | 5 +- drivers/md/bitmap.c | 4 +- drivers/md/md-cluster.c | 99 ++++++--- drivers/md/md.c | 44 +++- drivers/md/md.h | 5 +- drivers/md/raid5.c | 11 +- include/linux/raid/pq.h | 4 + lib/raid6/Makefile | 2 +- lib/raid6/algos.c | 12 + lib/raid6/avx512.c | 569 +++++++++++++++++++++++++++++++++++++++++++++++ lib/raid6/recov_avx512.c | 388 ++++++++++++++++++++++++++++++++ lib/raid6/test/Makefile | 5 +- lib/raid6/test/test.c | 7 +- lib/raid6/x86.h | 10 + 14 files changed, 1111 insertions(+), 54 deletions(-) create mode 100644 lib/raid6/avx512.c create mode 100644 lib/raid6/recov_avx512.c
