SubjectRE: [PATCH v7 0/8] Raid: enable talitos xor offload for improving performance
Date
Hi Vinod,

Would you like to apply this series from patch 2/8 to 7/8) in your tree?
The link as below,
http://patchwork.ozlabs.org/patch/176023/
http://patchwork.ozlabs.org/patch/176024/
http://patchwork.ozlabs.org/patch/176025/
http://patchwork.ozlabs.org/patch/176026/
http://patchwork.ozlabs.org/patch/176027/
http://patchwork.ozlabs.org/patch/176028/

After that, Herbert will merge patch 1/8, http://patchwork.ozlabs.org/patch/176022/
and Greg apply patch 8/8, http://patchwork.ozlabs.org/patch/176029/

Thanks.
