  nfs: make nfs4_drop_state_owner() static
  nfs: path_{get,put}() cleanups
  nfs: replace remaining __FUNCTION__ occurrences
  nfs/lsm: make NFSv4 set LSM mount options
  NFSv4: Check the return value of decode_compound_hdr_arg()
  nfs: fix race in nfs_dirty_request
  NFS: Ensure that 'noac' and/or 'actimeo=0' turn off attribute caching
