pre2 swap_out() changes

[Marcelo Tosatti <marcelo@conectiva.com.br>]

Hi Linus,

While looking at pre2 VM changes, I've saw this thing:

static int swap_out(unsigned int priority, int gfp_mask)
{
        int counter;
        int retval = 0;
        struct mm_struct *mm = current->mm;

        /* Always start by trying to penalize the process that is 
	allocating memory */
        if (mm)
                retval = swap_out_mm(mm, swap_amount(mm));


Since no process calls swap_out() directly, I dont see any sense on the
comment above. 

Is this really bogus or you're planning something?
