Hi Here I'm sending the dm-noclone patches. The patches improve performance for dm-linear and dm-stripe by avoid cloning the whole bio.
I deliberately decided to not support other targets becase: * they are more complicated, that means that we need larger noclone structure and large structure undoes the performance advantage * doubling the code paths of the endio function is bad for long-term maintenance Mikulas -- dm-devel mailing list [email protected] https://www.redhat.com/mailman/listinfo/dm-devel
