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.

Bart.
