Xiao Ni d981ed8419 md: Add new_level sysfs interface ... Now reshape supports two ways: with backup file or without backup file. For the situation without backup file, it needs to change data offset. It doesn't need systemd service mdadm-grow-continue. So it can finish the reshape job in one process environment. It can know the new level from mdadm --grow command and can change to new level after reshape finishes. For the situation with backup file, it needs systemd service mdadm-grow-continue to monitor reshape progress. So there are two process envolved. One is mdadm --grow command whick kicks off reshape and wakes up mdadm-grow-continue service. The second process is the service, which doesn't know the new level from the first process. In kernel space mddev->new_level is used to record the new level when doing reshape. This patch adds a new interface to help mdadm update new_level and sync it to metadata. Then mdadm-grow-continue can read the right new_level. Commit log revised by Song Liu. Please refer to the link for more details.
