Make sure that userspace does not retrieve stale asynchronous or
completion events after destroying a CQ, QP or SRQ. We do this by sweeping the event lists before returning from a destroy calls, and then return the number of events already reported before the destroy call. This allows userspace wait until it has processed all events for an object returned from the kernel before it frees its context for the object. The ABI of the destroy CQ, destroy QP and destroy SRQ commands has to change to return the event count, so bump the ABI version from 1 to 2. The userspace libibverbs library has already been updated to handle both the old and new ABI versions. Signed-off-by: Roland Dreier <rolandd@cisco.com>
