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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.

The current abstractions for batch vs single operations seem suboptimal and complicate the implementation of additional features (OOM, compaction). The immediate problem of the current abstractions is that they cause differences in how operations are handled when batching is on or off. For example, the refused_alloc counter is not updated when batching is on. These discrepancies are caused by code redundancies. Instead, this patch presents three type of operations, according to whether batching is on or off: (1) add page, (2) communication with the hypervisor and (3) retrieving the status of a page. To avoid the overhead of virtual functions, and since we do not expect additional interfaces for communication with the hypervisor, we use static keys instead of virtual functions. Finally, while we are at it, change vmballoon_init_batching() to return int instead of bool, to be consistent in the return type and avoid potential coding errors.
