I can run NVMe-RDMA (using ConnectX-5) in my lab till EOW and send the

Hello Max,

If this patch series impacts performance (which I doubt), it can only
impact the IB_WR_REG_SIG_MR work request. The SRP drivers do not yet
support T10-PI. Only the iSER initiator and target drivers submit
IB_WR_REG_SIG_MR work requests. Hence I'm not sure it is useful to
measure whether this patch series has any performance impact on the
SRP initiator and target drivers.


Agreed, I'll add my review for the patches.



Bart.
