This patch introduces mem_cgroup_charge_hugetlb which combines the logic of mem_cgroup_hugetlb_try_charge / mem_cgroup_hugetlb_commit_charge and removes the need for mem_cgroup_hugetlb_cancel_charge. It also reduces the footprint of memcg in hugetlb code and consolidates all memcg related error paths into one.

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 reStructuredText 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.
