Yes. We need copy these functions because they are not exported by the 
kernel of el5.

Because the struct splice_desc has been changed since 2.6.30, it it 
difficult to back port the latest code in mainline. So I chose the 
splice code in 2.6.29 for back porting. I hope the latest code before 
change are more stable and efficient.
