From: Matthew Wilcox <[email protected]>
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.
