you can get the file mapping & dump file blocks one at a time, anyway:

[root@bp-05 ~]# mount /dev/sdb4 /mnt/test
[root@bp-05 ~]# echo "mydata" > /mnt/test/testfile
[root@bp-05 ~]# ls -i /mnt/test/testfile
53573991 /mnt/test/testfile
[root@bp-05 ~]# umount /dev/sdb4


[root@bp-05 ~]# xfs_db /dev/sdb4
xfs_db> inode 53573991
xfs_db> p u.bmx
u.bmx[0] = [startoff,startblock,blockcount,extentflag] 0:[0,3348403,1,0]
xfs_db> fsblock 3348403
xfs_db> type text
xfs_db> p
000:  6d 79 64 61 74 61 0a 00 00 00 00 00 00 00 00 00  mydata..........
