flex_array: flex_array_prealloc takes a number of elements, not an end
Change flex_array_prealloc to take the number of elements for which space should be allocated instead of the last (inclusive) element. Users and documentation are updated accordingly. flex_arrays got introduced before they had users. When folks started using it, they ended up needing a different API than was coded up originally. This swaps over to the API that folks apparently need.

@@ -66,10 +66,10 @@ trick is to ensure that any needed memory allocations are done before
entering atomic context, using:
int flex_array_prealloc(struct flex_array *array, unsigned int start,
- unsigned int end, gfp_t flags);
+ unsigned int nr_elements, gfp_t flags);
This function will ensure that memory for the elements indexed in the range
-defined by start and end has been allocated. Thereafter, a
+defined by start and nr_elements has been allocated. Thereafter, a
flex_array_put() call on an element in that range is guaranteed not to
block.
