- Subject: [PATCH 14/14] Grow: Do not try to restart if reshape is running
- Grow process did not check if reshape is already started
- when deciding about restarting.
- Sync_action should be checked in this case, and if
- reshape is running - restart flag should not be set.
- Otherwise, Grow process will fail to write data to
- sysfs, and reshape will not be continued.
