It's observed that no more completion occurs after a few incorrect posts. Actually, it will block the polling. we can easily reproduce it by the below pattern. a. post correct RDMA_WRITE b. poll completion event while true { c. post incorrect RDMA_WRITE(wrong rkey for example) d. poll completion event <<<< block after 2 incorrect RDMA_WRITE posts } V4 add new patch from Bob where it make requester stop executing qp operation as soon as possible. Both blktests and pyverbs tests are passed fine.
