Program Since poller thread bears the brunt of execution till the request is handed over to io-threads, poller thread experiencies lock contention(s) in the control flow till io-threads, which slows it down. This delay invariably affects reading ping requests from network and responding to them, resulting in increased ping latencies, which sometimes results in a ping-timer-expiry on client leading to disconnect of transport. So, this patch aims to free up poller thread from executing code of Glusterfs Program. We do this by making * Glusterfs Program registering itself asking rpcsvc to execute its actors in its own threads. * GF-DUMP Program registering itself asking rpcsvc to _NOT_ execute its actors in its own threads. Otherwise program's ownthreads become bottleneck in processing ping traffic. This means that poller thread reads a ping packet, invokes its actor and hands the response msg to transport queue.
