I'd be a little concerned with that merge plan at this time - we have a lot of sata bug reports banked up and afaict a pretty low fixup rate. Then again, these patches might fix some of those bugs... I guess if we can get it all in early (which is only a couple of weeks away!) and you and Tejun will have time set aside to work on problems then OK.
