Here's how the real size is calculated before it's allocated:
static inline struct stripe_c *alloc_context(unsigned int stripes)
{
size_t len;
if (array_too_big(sizeof(struct stripe_c), sizeof(struct stripe),
stripes))
return NULL;
len = sizeof(struct stripe_c) + (sizeof(struct stripe) * stripes);
return kmalloc(len, GFP_KERNEL);
}
