From: Filip Bozuta <[email protected]> Target definitions of btrfs ioctls in 'syscall_defs.h' use the value BTRFS_IOCTL_MAGIC that is defined header 'btrfs.h'. This header is not available in kernel versions before 3.9. For that reason, these target ioctl definitions should be enwrapped in an #ifdef directive to check whether the 'btrfs.h' header is available as to not cause build errors on older Linux systems.
