From 74fe3057270fabb79f311414dd9c47c6245b52c7 Mon Sep 17 00:00:00 2001 From: Krishnan Parthasarathi Date: Tue, 28 May 2013 14:23:49 +0530 Subject: rpc: Cleanup rpc object in TRANSPORT_CLEANUP event rpc_transport object should be alive as long as the rpc_clnt object is alive. To ensure this, on rpc_clnt's last unref, we cleanup the corresponding rpc_transport object and complete the rpc_clnt cleanup later, in a bottom-up fashion. Introduced rpc_clnt_is_disabled, to allow higher layers to differentiate between the 'final'[1] disconnect triggered from upper layers, and a normal disconnect. This differentiation helps in cleaning up resources, at higher layers, in a race-free manner. [1] - 'final' here means that the rpc and the associated connection, is not going to be used anymore. eg - glusterd_brick_disconnect on volume-stop.
