Roland,
I made some mistakes during splitting these patches. Thanks for pointing out.
The reason I removed the cacheline because I have tested and proved that it didn't help somehow.
Even in some code, I induced some locks, the overall performance of all these 7 patches I am trying to post here could improve IPoIB from 20% - 80% unidirectional and doubled bidirectional.
As you mentioned I need help to repolish these patches. I am glad that you give all these valuable inputs of my patches. Thanks lots here.
Thanks
