Subject: [PATCH] util: Export virStorageFileSupportsBackingChainTraversal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function will be reused in the qemu snapshot code. The argument is
turned into const similarly to the other virStorageFileSupports*
functions.
