From: Prasanna Kumar Kalever <prasanna.kale...@redhat.com> New versions of Glusters libgfapi.so have an updated glfs_ftruncate() function that returns additional 'struct stat' structures to enable advanced caching of attributes. This is useful for file servers, not so much for QEMU. Nevertheless, the API has changed and needs to be adopted.
