NAME
       seq_open - initialize sequential file

SYNOPSIS
       int seq_open(struct file * file, const struct seq_operations * op);

ARGUMENTS
       file
	   file we initialize

       op
	   method table describing the sequence

DESCRIPTION
       seq_open sets file, associating it with a sequence described by op.
       op->start sets the iterator up and returns the first element of
       sequence.  op->stop shuts it down.  op->next returns the next element
       of sequence.  op->show prints element into the buffer. In case of error
       ->start and ->next return ERR_PTR(error). In the end of sequence they
       return NULL. ->show returns 0 in case of success and negative number in
       case of error. Returning SEQ_SKIP means “discard this element and move
       on”.
