The following patches implememt what is needed for rbd to be able to implment SCSI WRITE_SAME and COMPARE_AND_WRITE support. This is needed when we export rbd devices to ESXi using iSCSI or FC or whatever your favorite SCSI transport is. Basically, ESXi uses these commands to do things like thin provisioning and locking.
