Zbyszek, i research problem and i found what in btrfs.h
struct btrfs_ioctl_defrag_range_args  not defined
This acceptable if i add it in missing.h like:
/* btrfs_ioctl_defrag_range_args now 21.07.2014
 * not defined in btrfs.h and duplicated from <kernel>/fs/btrfs/ctree.h
 */
#ifdef HAVE_LINUX_BTRFS_H
struct btrfs_ioctl_defrag_range_args {
        uint64_t start;         /* start byte = 0 */
        uint64_t len;           /* whole file uint64_t-1 */
        uint64_t flags;         /* start_io 2 */
        uint32_t extent_thresh; /* 0 */
        uint32_t compress_type;
        uint32_t unused[4];
};
#endif

Best regards,
Timofey.
