[ Upstream commit 96403bfe50c344b587ea53894954a9d152af1c9d ]
SLUB currently account kmalloc() and kmalloc_node() allocations larger
than order-1 page per-node. But it forget to update the per-memcg
vmstats. So it can lead to inaccurate statistics of "slab_unreclaimable"
which is from memory.stat. Fix it by using mod_lruvec_page_state instead
of mod_node_page_state.

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.
