Subject: Re: [PATCH RFC v2] slab: introduce kmalloc_array

Here goes a quick summary.

Proposed names
==============

kaalloc        (Alexey Dobriyan)

kcallocn       (Andrew Morton)

kmalloc_array  (Pekka Enberg)

knalloc        (Andrew Morton, Xi Wang)

kncalloc       (Andrew Morton)

Other changes
=============

Documentation/CodingStyle "Chapter 14: Allocating memory"

* Mention the new array allocator whatever-it-is-called.

* Add some description:

"The preferred form for allocating an array is the following:

	p = whatever-it-is-called(n, sizeof(...), ...);

To return zeroed items, the preferred form is the following: 

	p = kcalloc(n, sizeof(...), ...);

Both forms avoid overflowing the allocation size n * sizeof(...)."

* Add some checkpatch rule?
