[PATCH 0/2] Add kvzalloc_struct to complement kvzalloc_array

[Matthew Wilcox]

From: Matthew Wilcox <mawilcox@xxxxxxxxxxxxx>

We all know the perils of multiplying a value provided from userspace
by a constant and then allocating the resulting number of bytes.  That's
why we have kvmalloc_array(), so we don't have to think about it.
This solves the same problem when we embed one of these arrays in a
struct like this:

struct {
	int n;
	unsigned long array[];
};

Using kvzalloc_struct() to allocate this will save precious thinking
time and reduce the possibilities of bugs.

  mm: Add kernel-doc for kvfree
  mm: Add kvmalloc_ab_c and kvzalloc_struct
