NFS client updates for Linux 4.6

Highlights include:

Features:
- Add support for multiple NFSv4.1 callbacks in flight
- Initial patchset for RPC multipath support
- Adapt RPC/RDMA to use the new completion queue API

Bugfixes and cleanups:
- nfs4: nfs4_ff_layout_prepare_ds should return NULL if connection failed
- Cleanups to remove nfs_inode_dio_wait and nfs4_file_fsync
- Fix RPC/RDMA credit accounting
- Properly handle RDMA_ERROR replies
- xprtrdma: Do not wait if ib_post_send() fails
- xprtrdma: Segment head and tail XDR buffers on page boundaries
- xprtrdma cleanups for dprintk, physical_op_map and unused macros

      xprtrdma: Use new CQ API for RPC-over-RDMA client send CQs

Jeff Layton (1):
      nfs4: nfs4_ff_layout_prepare_ds should return NULL if connection failed

Kinglong Mee (1):
      nfs/blocklayout: make sure making a aligned read request

Trond Myklebust (22):

      Merge branch 'nfsv41_cb'
      Merge branch 'multipath'
      Merge tag 'nfs-rdma-4.6-1' of git://git.linux-nfs.org/projects/anna/nfs-rdma
