Anton Ivanov 54ebe4060f um: Use fdatasync() when mapping the UBD FSYNC command ... We do not need to update the metadata (atime, mtime, etc) on the UBD file and/or the COW file until UML exits. UBD image mtime is checked in UML only when opening the files. After that they are locked and used exclusively by a single UML instance, so there is no point wasting resources on updating metadata on every sync. We can sync data only. The host will always update mtime if a file has been modified upon closing it.
