Subject: [PATCH] util: virstoragefile: Add data structure for storing storage
source slices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Introduce virStorageSourceSlice which will store the 'offset' and 'size'
of a virStorageSource and declare it as 'sliceStorage' and 'sliceFormat'
attributes of a virStorageSource.
