    fuse: fix pipe_buf_operations · 28a625cb
    Miklos Szeredi authored
    Having this struct in module memory could Oops when if the module is
    unloaded while the buffer still persists in a pipe.
    
    Since sock_pipe_buf_ops is essentially the same as fuse_dev_pipe_buf_steal
    merge them into nosteal_pipe_buf_ops (this is the same as
    default_pipe_buf_ops except stealing the page from the buffer is not
    allowed).
