Hello Sagi,
Can you clarify this further ? Removing the IB_SEND_SIGNALED flag from
send requests is not possible because that would result in the HCA only
delivering work completions for failed work requests to the SRP
initiator driver. The loop in srp_send_completion() also needs the work
completions for send work requests that succeeded. In other words, it's
not clear to me what you were referring to ?
Bart.
