It is v4.14-rc1+, and top commit is 8d93c7a43157, with all your 7 patches
applied.

Follows my pm test script:
#!/bin/sh
echo check > /sys/block/md127/md/sync_action
mkfs.ext4 -F /dev/md127
mount /dev/md0 /mnt/data
dd if=/dev/zero of=/mnt/data/d1.img bs=4k count=128k&
echo 9 > /proc/sys/kernel/printk
echo devices > /sys/power/pm_test
echo mem > /sys/power/state
wait
umount /mnt/data
Storage setting:
sudo mdadm --create /dev/md/test /dev/sda /dev/sdb --level=1
--raid-devices=2
both /dev/sda and /dev/sdb are virtio-scsi.
