> The process of loading a file system image involves reading inodes section, 
> deserializing inodes, initializing inodes, adding inodes to the global map, 
> reading directories section, adding inodes to their parents' map, cache name 
> etc. These steps can be done in a pipeline model to reduce the total 
> duration.
