Linus Torvalds 7f155c7026 NFS client updates for Linux 4.8
Highlights include:
 
 Stable bugfixes:
  - nfs: don't create zero-length requests
  - Several LAYOUTGET bugfixes
 
 Features:
  - Several performance related features
    - More aggressive caching when we can rely on close-to-open cache
      consistency
    - Remove serialisation of O_DIRECT reads and writes
    - Optimise several code paths to not flush to disk unnecessarily. However
      allow for the idiosyncracies of pNFS for those layout types that need
      to issue a LAYOUTCOMMIT before the metadata can be updated on the server.
    - SUNRPC updates to the client data receive path
  - pNFS/SCSI support RH/Fedora dm-mpath device nodes
  - pNFS files/flexfiles can now use unprivileged ports when the generic NFS
    mount options allow it.
 
 Bugfixes:
  - Don't use RDMA direct data placement together with data integrity or
    privacy security flavours
  - Remove the RDMA ALLPHYSICAL memory registration mode as it has potential
    security holes.
  - Several layout recall fixes to improve NFSv4.1 protocol compliance.
  - Fix an Oops in the pNFS files and flexfiles connection setup to the DS
  - Allow retry of operations that used a returned delegation stateid
  - Don't mark the inode as revalidated if a LAYOUTCOMMIT is outstanding
  - Fix writeback races in nfs4_copy_range() and nfs42_proc_deallocate()
