Fix for non-ncq ncq commands causing timeouts when both are issued
simultaneously to the same device.

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.
Thanks,
Ashish

already

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

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 ).
