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
