sector_t is defined by include/linux/types.h as follows.
#ifdef CONFIG_LBDAF
typedef u64 sector_t;
typedef u64 blkcnt_t;
#else
typedef unsigned long sector_t;
typedef unsigned long blkcnt_t;
#endif
Therefore, I think that you should change the code as follows.
printk(KERN_ERR "btrfs direct IO failed ino %lu rw %lu "
"disk_bytenr %llu len %u err no %d\n",
dip->inode->i_ino, bio->bi_rw,
(u64)bio->bi_sector, bio->bi_size, err);
