Struct btrfs_diskformat::DevExtent [−][src]
Maps physical extents on an individual backing device to a chunk. This extent may be the only one for a particular chunk or one of several.
It is associated with the DEV_ITEM
item. This structure is never used
outside of this item.
Fields
chunk_tree: U64<LE>
The object ID of the chunk tree that owns this extent.
chunk_objectid: U64<LE>
The object ID of the chunk item that references this extent.
chunk_offset: U64<LE>
The offset of the chunk item that references this extent.
length: U64<LE>
The length of this extent, in bytes.
chunk_tree_uuid: UuidBytes
The UUID of the chunk tree that owns this extent.
