Subject: [PATCH] virStorageFileGetMetadataRecurse: Remove impossible error
report
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We call virStorageFileSupportsBackingChainTraversal which already checks
that the 'storageFileRead' callback is non-NULL, which in turn means
that virStorageFileRead will not return -2.
