Message-Id: <c6a7e638954bbcb8679966f31ce398d97fa1aca1@dist-git>

Subject: [PATCH] virDomainDiskTranslateSourcePool: split code to setup one
storage source
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Extract all the code setting up one storage source from the rest which
sets up the whole disk. This will allow us to prepare the whole backing
chain.
