Description

We can't always guess file layouts correctly. Provide a mechanism for users to manually specify the file layout to be used for injected inodes, along with a path filter.

For inodes whose backtraces match the path filter, apply the overridden layout. Warn if the overridden layout is inconsistent with the object sizes seen.

Support input of the path->layout mappings from a file, as for users with custom layouts it's quite possible they'll have many dirs with different layouts.
