    NFSv4: fix delegated locking
    
    Arnaud Giersch reports that NFSv4 locking is broken when we hold a
    delegation since commit 8e469ebd6dc32cbaf620e134d79f740bf0ebab79 (NFSv4:
    Don't allow posix locking against servers that don't support it).
    
    According to Arnaud, the lock succeeds the first time he opens the file
    (since we cannot do a delegated open) but then fails after we start using
    delegated opens.
    
    The following patch fixes it by ensuring that locking behaviour is
    governed by a per-filesystem capability flag that is initially set, but
    gets cleared if the server ever returns an OPEN without the
    NFS4_OPEN_RESULT_LOCKTYPE_POSIX flag being set.

    NFS: Ensure that the WRITE and COMMIT RPC calls are always uninterruptible
    
    We always want to ensure that WRITE and COMMIT completes, whether or not
    the user presses ^C. Do this by making the call asynchronous, and allowing
    the user to do an interruptible wait for rpc_task completion.

    NFS: Fix a race with the new commit code
    
    This patch fixes a race which occurs due to the fact that we release the
    PG_writeback flag while still holding the nfs_page locked.

    NFS: Ensure that writeback_single_inode() calls write_inode() when syncing
    
    Since writeback_single_inode() checks the inode->i_state flags _before_ it
    flushes out the data, we need to ensure that the I_DIRTY_DATASYNC flag is
    already set. Otherwise we risk not seeing a call to write_inode(), which
    again means that we break fsync() et al...
