2016-07-16SUNRPC: Fix infinite looping in rpc_clnt_iterate_for_each_xprtTrond Myklebust
If there were less than 2 entries in the multipath list, then xprt_iter_next_entry_multiple() would never advance beyond the first entry, which is correct for round robin behaviour, but not for the list iteration. The end result would be infinite looping in rpc_clnt_iterate_for_each_xprt() as we would never see the xprt == NULL condition fulfilled.

2016-02-05SUNRPC: Add a structure to track multiple transportsTrond Myklebust
In order to support multipathing/trunking we will need the ability to track multiple transports. This patch sets up a basic structure for doing so. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
