Thanks Jens,
 However I've just today discovered that the very first patch causes a real
 regression in throughput for RAID5 and while I'm sure I can fix it with a
 subsequent patch (once I figure out exactly what it happening) it might ma=
ke
 sense to hold them all back for 3.7.

 However if you would like to take them now and fix up later (it is only a
 performance regression so it won't really affect bisection) I can work with
 that.

Thanks,
NeilBrown
