摘要：
Using metadata for a contentless file to provide a guest context access to file content. Within a guest context, a filesystem is mounted from a container image which lacks a first file's content and which includes metadata defining properties of the first file and mapping data defining information for identifying a second file within another filesystem from which the first file's content is obtainable. Based on the properties, a filesystem operation involving the first file is performed without switching to a host context, and a requested access to the first file's content is responded to. Responding includes, based on the mapping data, communicating a request for the host context to supply the first file's content and, after returning from a context switch, responding to the requested access by supplying content of the second file from guest memory page(s) which are mapped to host memory page(s) containing the second file's content.
