- Bugfix: don't use rename() to create file copies from the LZ to storage pool drives, even if they are the same device, when 'allow_multiple_sp_per_device' is enabled. This can creates issues when the LZ and multiple storage pool drives are on the same device.
- Fixed infinite loop when a fsck wants fsck_file tasks to be executed first, but those tasks IDs are larger than the fsck task.
