Hello Kumar,

This doesn't look like it should change anything. sata_fsl_ops 

inherits

from sata_pmp_port_ops, which inherits from sata_port_ops, which 

already

sets qc_defer to ata_std_qc_defer.

Oh, yes. Actually this patch was for older kernels where there 
inheritence was not there. As you mentioned, this patch is not 
required now.

How old?  Should we be asking for this to be applied to some of the 
stable kernel series?

I believe that the inheritence stuff was added in 2.6.26, thus, this patch is
required for quite old kernels ( < 2.6.26 ).

Thanks,

Ashish
