A particular numbered inode always lives in the same place on the
disk. When choosing what inode to use for a new file, the filesystem
tries to pick a inode to put the file close to the directory it is
being created in. This is the dirpref optimisation introduced a few
years ago - previously inodes were chosen from a part of a disk that
had the most nearby free space.
