Btrfs: Fix file clone when source offset is not 0 Suppose: - the source extent is: [0, 100] - the src offset is 10 - the clone length is 90 - the dest offset is 0 This statement: new_key.offset = key.offset + destoff - off will produce such an extent for the dest file: [ino, BTRFS_EXTENT_DATA_KEY, -10] , which is obviously wrong.
