Right now, we are allocating virStorageFileMetadata near the bottom of the callchain, only after we have identified that we are visiting a file (and not a network resource). I'm hoping to eventually support parsing the backing chain from XML, where the backing chain crawl then validates what was parsed rather than allocating a fresh structure. Likewise, I'm working towards a setup where we have a backing element even for networks. Both of these use cases are easier to code if the allocation is hoisted earlier. * src/util/virstoragefile.c (virStorageFileGetMetadataInternal) (virStorageFileGetMetadataFromFDInternal): Change signature. (virStorageFileGetMetadataFromBuf) (virStorageFileGetMetadataRecurse, virStorageFileGetMetadata): Update callers. Signed-off-by: NEric Blake <eblake@redhat.com>
