Pull NFS client updates from Trond Myklebust: "Another set of mainly bugfixes and a couple of cleanups. No new functionality in this round.

NFS: Move nfs_idmap.h into fs/nfs/

2015-04-23T19:16:14+00:00

This file is only used internally to the NFS v4 module, so it doesn't need to be in the global include path. I also renamed it from nfs_idmap.h to nfs4idmap.h to emphasize that it's an NFSv4-only include file. Signed-off-by: Anna Schumaker Signed-off-by: Trond Myklebust

NFSv4: Fix a race in NFSv4.1 server trunking discovery

2015-03-04T01:42:23+00:00

We do not want to allow a race with another NFS mount to cause nfs41_walk_client_list() to establish a lease on our nfs_client before we're done checking for trunking. Signed-off-by: Trond Myklebust

NFSv4.1: Fix an Oops in nfs41_walk_client_list

NFS: Ignore transport protocol when detecting server trunking

2015-01-06T03:40:54+00:00

Detect server trunking across transport protocols. Otherwise, an RDMA mount and a TCP mount of the same server will end up with separate nfs_clients using the same clientid4. Reported-by: Dai Ngo Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust
