====================
Fix the unmatched unit_size of bpf_mem_cache

From: Hou Tao <houtao1@huawei.com>

Hi,

The patchset aims to fix the reported warning [0] when the unit_size of
bpf_mem_cache is mismatched with the object size of underly slab-cache.

Patch #1 fixes the warning by adjusting size_index according to the
value of KMALLOC_MIN_SIZE, so bpf_mem_cache with unit_size which is
smaller than KMALLOC_MIN_SIZE or is not aligned with KMALLOC_MIN_SIZE
will be redirected to bpf_mem_cache with bigger unit_size. Patch #2
doesn't do prefill for these redirected bpf_mem_cache to save memory.
Patch #3 adds further error check in bpf_mem_alloc_init() to ensure the
unit_size and object_size are always matched and to prevent potential
issues due to the mismatch.

Please see individual patches for more details. And comments are always
welcome.

README

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.
