* protocol/rpc/transport: bring in one more event for 'TRANSPORT-DESTROY'Amar Tumballi2010-10-071-1/+5
| | | | | | | | | | | | needed because, a RPC disconnect doesn't mean that a RPC transport/listener is dead. With this, the race in server protocol cleaning up the lock table / fd table when some frames are in transit will be handled properly.

| | | | | | | | | | | | | | | | | | | Submitted-by: Krishna Srinivas <krishna@gluster.com> NOTE: fixed compilation issues in posix.c introduced while merging storage/posix polls for FS/kernel being functional by issuing statvfs() call. In case statvfs expires the timer, storage/posix will send CHILD_DOWN to upper translator. Ultimately this will cause protocol/server to disconnect all clients connected and also cleans up the data structures. Hence if soft lockup or other kernel bug causes backend FS to hang, the clients will not be hung. Signed-off-by: Krishna Srinivas <krishna@gluster.com> Signed-off-by: Anand V.
