Historically rdmavt destroy_ah() has returned an -EBUSY when the AH has a non-zero reference count. IBTA 11.2.2 notes no such return value or error case: Output Modifiers: - Verb results: - Operation completed successfully. - Invalid HCA handle. - Invalid address handle. ULPs never test for this error and this will leak memory. The reference count exists to allow for driver independent progress mechanisms to process UD SWQEs in parallel with post sends. The SWQE will hold a reference count until the UD SWQE completes and then drops the reference. Fix by removing need to reference count the AH. Add a UD specific allocation to each SWQE entry to cache the necessary information for independent progress. Copy the information during the post send processing.
