Struct RescueFixDeviceSizeCommand 

pub struct RescueFixDeviceSizeCommand { /* private fields */ }

Re-align device and super block sizes

Recomputes each device’s total_bytes from its physical size and the device extent layout, updates the corresponding DEV_ITEM in the chunk tree (and the embedded dev_item in the superblock), and rewrites the superblock’s total_bytes to match the sum.

Cases handled:

• dev_item.total_bytes is misaligned to sectorsize: round it down.
• dev_item.total_bytes is larger than the underlying block device or backing file: shrink it to the actual size, but only if no DEV_EXTENT covers or extends past that boundary (otherwise we’d lose data).

The device must not be mounted.
