What we do know is that a subsequent LOCAL_INVALIDATE using the rkey that should work (if FAST_REG_MR had indeed never been done) fails in some cases.

Steve can provide more detail about the exact failure mode with cxgb4. -- Chuck Lever chuck[dot]lever[at]oracle[dot]com -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
