And why do you think that would matter the slightest?
I noticed that the same cq functions are used. And I also made tests with this patch series. Without this patch series, dim mechanism will not be invoked.
Christoph alluded to say: Do not modify the old cq_create_cq() code in order to support DIM, it is better to change the ULP to use ib_alloc_cq(), and get DIM enabled that way.
Hi, Haakon
To be honest, I like your original commit that enable DIM for legacy
ULPs because this can fix this problem once for all and improve the old
ib_create_cq function.
The idea from Christoph will cause a lot of changes in ULPs. I am not
very sure if these changes cause risks or not.
Thus, I prefer to your original commit. But I will follow the advice
from Leon and Jason.
