Hi,

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

=46rom 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 =3D (struct vm_struct *) kmalloc(sizeof(*area), GFP_KERNEL);
	if (!area)
		return NULL;
	size +=3D PAGE_SIZE;
	^^^^^^^^^^^^^^^^^^
Why ? Maybe size =3D PAGE_ALIGN(size); is more correct here ?

Best regards.
