NFS client updates for Linux 4.3

Browse source 
Highlights include:
 
 Stable patches:
 - Fix atomicity of pNFS commit list updates
 - Fix NFSv4 handling of open(O_CREAT|O_EXCL|O_RDONLY)
 - nfs_set_pgio_error sometimes misses errors
 - Fix a thinko in xs_connect()
 - Fix borkage in _same_data_server_addrs_locked()
 - Fix a NULL pointer dereference of migration recovery ops for v4.2 client
 - Don't let the ctime override attribute barriers.
 - Revert "NFSv4: Remove incorrect check in can_open_delegated()"
 - Ensure flexfiles pNFS driver updates the inode after write finishes
 - flexfiles must not pollute the attribute cache with attrbutes from the DS
 - Fix a protocol error in layoutreturn
 - Fix a protocol issue with NFSv4.1 CLOSE stateids
 
 Bugfixes + cleanups
 - pNFS blocks bugfixes from Christoph
 - Various cleanups from Anna
 - More fixes for delegation corner cases
 - Don't fsync twice for O_SYNC/IS_SYNC files
 - Fix pNFS and flexfiles layoutstats bugs
 - pnfs/flexfiles: avoid duplicate tracking of mirror data
 - pnfs: Fix layoutget/layoutreturn/return-on-close serialisation issues.
 - pnfs/flexfiles: error handling retries a layoutget before fallback to MDS
 
 Features:
 - Full support for the OPEN NFS4_CREATE_EXCLUSIVE4_1 mode from Kinglong
 - More RDMA client transport improvements from Chuck
 - Removal of the deprecated ib_reg_phys_mr() and ib_rereg_phys_mr() verbs
   from the SUNRPC, Lustre and core infiniband tree.
 - Optimise away the close-to-open getattr if there is no cached data
