Subject[Q] get_ma_area() function

looking at mm/vmalloc.c i found one strange (for me) line of code.

From mm/vmalloc.c:

struct vm_struct * get_vm_area(unsigned long size, unsigned long flags)
unsigned long addr;
struct vm_struct **p, *tmp, *area;

area = (struct vm_struct *) kmalloc(sizeof(*area), GFP_KERNEL);
if (!area)
return NULL;
size += PAGE_SIZE;
Why ? Maybe size = PAGE_ALIGN(size); is more correct here ?

Best regards.
