use int64_t for return values from rbd instead of int
rbd / rados tends to return pretty often length of writes or discarded blocks. These values might be bigger than int. The steps to reproduce are: mkfs.xfs -f a whole device bigger than int in bytes. mkfs.xfs sends a discard. Important is that you use scsi-hd and set discard_granularity=512. Otherwise rbd disabled discard support. Signed-off-by: Stefan Priebe <s.priebe@profihost.ag> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
