> inodes is initialized with the number of patch components. After resolve, it contains
both non-null and null elements (introduced by dot-snapshot dirs).
> When getINodes is called, an array is returned excluding all non elements, which is the
correct behavior. Meanwhile, the inodes array is trimmed too, which shouldn't be done by a
getter.
> Because of the above, the behavior of getINodesInPath depends on whether getINodes has
been called, which is not correct.
> The name of getLastINodeInPath is confusing – it actually returns the last non-null
inode in the path. Also, shouldn't the return type be a single INode?
