Re: [libvirt] [PATCH 1/6] conf: track user vs. canonical name through full chain lookup

The previous patch started a separation of error messages reported against the user-specified name, vs. tracking the canonical path that was actually opened. This patch extends that notion, by hoisting directory detection up front, passing the canonical path through the entire call chain, and simplifying lower-level functions that can now assume that a canonical path and directory have been supplied. * src/util/virstoragefile.c (virStorageFileGetMetadataFromFDInternal) (virStorageFileGetMetadataInternal): Add parameter, require directory. (virFindBackingFile): Require directory. (virStorageFileGetMetadataFromFD): Pass canonical path. (virStorageFileGetMetadataFromBuf): Likewise. (virStorageFileGetMetadata): Determine initial directory.
