NFS: Fix a race between mmap() and O_DIRECT (2018-01-28 22:00:15 -0500)

----------------------------------------------------------------
NFS client updates for Linux 4.16

Highlights include:

Stable bugfixes:
- Fix breakages in the nfsstat utility due to the inclusion of the NFSv4
LOOKUPP operation.
- Fix a NULL pointer dereference in nfs_idmap_prepare_pipe_upcall() due to
nfs_idmap_legacy_upcall() being called without an 'aux' parameter.
- Fix a refcount leak in the standard O_DIRECT error path.
- Fix a refcount leak in the pNFS O_DIRECT fallback to MDS path.
- Fix CPU latency issues with nfs_commit_release_pages()
- Fix the LAYOUTUNAVAILABLE error case in the file layout type.
- NFS: Fix a race between mmap() and O_DIRECT

Features:
- Support the statx() mask and query flags to enable optimisations when
the user is requesting only attributes that are already up to date in
the inode cache, or is specifying the AT_STATX_DONT_SYNC flag.
- Add a module alias for the SCSI pNFS layout type.

Bugfixes:
- Automounting when resolving a NFSv4 referral should preserve the RDMA
transport protocol settings.
- Various other RDMA bugfixes from Chuck.
- pNFS block layout fixes.
- Always set NFS_LOCK_LOST when a lock is lost.
