    NFS: Fix another nfs_wb_page() deadlock
    
    J.R. Okajima reports that the call to sync_inode() in nfs_wb_page() can
    deadlock with other writeback flush calls. It boils down to the fact
    that we cannot ever call writeback_single_inode() while holding a page
    lock (even if we do set nr_to_write to zero) since another process may
    already be waiting in the call to do_writepages(), and so will deny us
    the I_SYNC lock.

    NFS: Ensure that we mark the inode as dirty if we exit early from commit
    
    If we exit from nfs_commit_inode() without ensuring that the COMMIT rpc
    call has been completed, we must re-mark the inode as dirty. Otherwise,
    future calls to sync_inode() with the WB_SYNC_ALL flag set will fail to
    ensure that the data is on the disk.
