Patch series "slab: provide and use krealloc_array()", v3. Andy brought to my attention the fact that users allocating an array of equally sized elements should check if the size multiplication doesn't overflow. This is why we have helpers like kmalloc_array(). However we don't have krealloc_array() equivalent and there are many users who do their own multiplication when calling krealloc() for arrays. This series provides krealloc_array() and uses it in a couple places. A separate series will follow adding devm_krealloc_array() which is needed in the xilinx adc driver. This patch (of 9): __GFP_ZERO is ignored by krealloc() (unless we fall-back to kmalloc() path, in which case it's honored). Point that out in the kerneldoc.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
