[PATCH 00/10] locking fixups for NFS

[Benjamin Coddington <bcodding@redhat.com>]

This set addresses a few NFS related locking issues as well as a couple
minor cleanups.  It does a bit of plumbing to make sure we can complete
unlocks after close when the fl_file may be unavailable, and it attempts to
always release locks even when a wait for oustanding IO is interrupted
before sending an unlock.  This can orphan a lock on a server, which might
mean a delay for matching lock NFS4, or require a server restart to clean up
that lock for NFS3.

Benjamin Coddington (10):
  NFS: keep nfs4_state for nfs4_lock_state cleanup
  NFS4: remove a redundant lock range checks
  NFS: Move the flock open mode check into nfs_flock()
  NFS: Pass nfs_open_context instead of file to the lock procs
  NFSv4: Pass nfs_open_context instead of nfs4_state to
    nfs4_proc_unlck()
  lockd: Plumb nfs_open_context into nlm client unlock
  lockd: Send the inode to nlmclnt_setlockargs()
  NFS: Move do_vfs_lock to shared inline
  locks: Use more file_inode and fix a comment
  NFS: Deferred unlocks - always unlock on FL_CLOSE
