[libvirt] [PATCH 6/6] conf: delete internal directory field

Fri Apr 11 04:21:31 UTC 2014
Another field no longer needed, getting us one step closer to
merging virStorageFileMetadata and virStorageSource.
* src/util/virstoragefile.h (_virStorageFileMetadata): Drop
field.
* src/util/virstoragefile.c (virStorageFileGetMetadataInternal)
(virStorageFileGetMetadataFromFDInternal): Alter signature.
(virStorageFileFreeMetadata, virStorageFileGetMetadataFromBuf)
(virStorageFileGetMetadataFromFD): Adjust clients.
* tests/virstoragetest.c (_testFileData, testStorageChain)
(mymain): Simplify test.
